--- Day 10: Pipe Maze ---
|
||||
You use the hang glider to ride the hot air from Desert Island all the way up to the floating metal island. This island is surprisingly cold and there definitely aren't any thermals to glide on, so you leave your hang glider behind.
|
||||
|
||||
You wander around for a while, but you don't find any people or animals. However, you do occasionally find signposts labeled "Hot Springs" pointing in a seemingly consistent direction; maybe you can find someone at the hot springs and ask them where the desert-machine parts are made.
|
||||
|
||||
The landscape here is alien; even the flowers and trees are made of metal. As you stop to admire some metal grass, you notice something metallic scurry away in your peripheral vision and jump into a big pipe! It didn't look like any animal you've ever seen; if you want a better look, you'll need to get ahead of it.
|
||||
|
||||
Scanning the area, you discover that the entire field you're standing on is densely packed with pipes; it was hard to tell at first because they're the same metallic silver color as the "ground". You make a quick sketch of all of the surface pipes you can see (your puzzle input).
|
||||
|
||||
The pipes are arranged in a two-dimensional grid of tiles:
|
||||
|
||||
| is a vertical pipe connecting north and south.
|
||||
- is a horizontal pipe connecting east and west.
|
||||
L is a 90-degree bend connecting north and east.
|
||||
J is a 90-degree bend connecting north and west.
|
||||
7 is a 90-degree bend connecting south and west.
|
||||
F is a 90-degree bend connecting south and east.
|
||||
. is ground; there is no pipe in this tile.
|
||||
S is the starting position of the animal; there is a pipe on this tile, but your sketch doesn't show what shape the pipe has.
|
||||
Based on the acoustics of the animal's scurrying, you're confident the pipe that contains the animal is one large, continuous loop.
|
||||
|
||||
For example, here is a square loop of pipe:
|
||||
|
||||
.....
|
||||
.F-7.
|
||||
.|.|.
|
||||
.L-J.
|
||||
.....
|
||||
If the animal had entered this loop in the northwest corner, the sketch would instead look like this:
|
||||
|
||||
.....
|
||||
.S-7.
|
||||
.|.|.
|
||||
.L-J.
|
||||
.....
|
||||
In the above diagram, the S tile is still a 90-degree F bend: you can tell because of how the adjacent pipes connect to it.
|
||||
|
||||
Unfortunately, there are also many pipes that aren't connected to the loop! This sketch shows the same loop as above:
|
||||
|
||||
-L|F7
|
||||
7S-7|
|
||||
L|7||
|
||||
-L-J|
|
||||
L|-JF
|
||||
In the above diagram, you can still figure out which pipes form the main loop: they're the ones connected to S, pipes those pipes connect to, pipes those pipes connect to, and so on. Every pipe in the main loop connects to its two neighbors (including S, which will have exactly two pipes connecting to it, and which is assumed to connect back to those two pipes).
|
||||
|
||||
Here is a sketch that contains a slightly more complex main loop:
|
||||
|
||||
..F7.
|
||||
.FJ|.
|
||||
SJ.L7
|
||||
|F--J
|
||||
LJ...
|
||||
Here's the same example sketch with the extra, non-main-loop pipe tiles also shown:
|
||||
|
||||
7-F7-
|
||||
.FJ|7
|
||||
SJLL7
|
||||
|F--J
|
||||
LJ.LJ
|
||||
If you want to get out ahead of the animal, you should find the tile in the loop that is farthest from the starting position. Because the animal is in the pipe, it doesn't make sense to measure this by direct distance. Instead, you need to find the tile that would take the longest number of steps along the loop to reach from the starting point - regardless of which way around the loop the animal went.
|
||||
|
||||
In the first example with the square loop:
|
||||
|
||||
.....
|
||||
.S-7.
|
||||
.|.|.
|
||||
.L-J.
|
||||
.....
|
||||
You can count the distance each tile in the loop is from the starting point like this:
|
||||
|
||||
.....
|
||||
.012.
|
||||
.1.3.
|
||||
.234.
|
||||
.....
|
||||
In this example, the farthest point from the start is 4 steps away.
|
||||
|
||||
Here's the more complex loop again:
|
||||
|
||||
..F7.
|
||||
.FJ|.
|
||||
SJ.L7
|
||||
|F--J
|
||||
LJ...
|
||||
Here are the distances for each tile on that loop:
|
||||
|
||||
..45.
|
||||
.236.
|
||||
01.78
|
||||
14567
|
||||
23...
|
||||
Find the single giant loop starting at S. How many steps along the loop does it take to get from the starting position to the point farthest from the starting position?
|
||||
|
||||
Your puzzle answer was 6882.
|
||||
|
||||
The first half of this puzzle is complete! It provides one gold star: *
|
||||
|
||||
--- Part Two ---
|
||||
You quickly reach the farthest point of the loop, but the animal never emerges. Maybe its nest is within the area enclosed by the loop?
|
||||
|
||||
To determine whether it's even worth taking the time to search for such a nest, you should calculate how many tiles are contained within the loop. For example:
|
||||
|
||||
...........
|
||||
.S-------7.
|
||||
.|F-----7|.
|
||||
.||.....||.
|
||||
.||.....||.
|
||||
.|L-7.F-J|.
|
||||
.|..|.|..|.
|
||||
.L--J.L--J.
|
||||
...........
|
||||
The above loop encloses merely four tiles - the two pairs of . in the southwest and southeast (marked I below). The middle . tiles (marked O below) are not in the loop. Here is the same loop again with those regions marked:
|
||||
|
||||
...........
|
||||
.S-------7.
|
||||
.|F-----7|.
|
||||
.||OOOOO||.
|
||||
.||OOOOO||.
|
||||
.|L-7OF-J|.
|
||||
.|II|O|II|.
|
||||
.L--JOL--J.
|
||||
.....O.....
|
||||
In fact, there doesn't even need to be a full tile path to the outside for tiles to count as outside the loop - squeezing between pipes is also allowed! Here, I is still within the loop and O is still outside the loop:
|
||||
|
||||
..........
|
||||
.S------7.
|
||||
.|F----7|.
|
||||
.||OOOO||.
|
||||
.||OOOO||.
|
||||
.|L-7F-J|.
|
||||
.|II||II|.
|
||||
.L--JL--J.
|
||||
..........
|
||||
In both of the above examples, 4 tiles are enclosed by the loop.
|
||||
|
||||
Here's a larger example:
|
||||
|
||||
.F----7F7F7F7F-7....
|
||||
.|F--7||||||||FJ....
|
||||
.||.FJ||||||||L7....

.....|FJLJ|FJ|F7|.LJ
|
||||
....FJL-7.||.||||...
|
||||
....L---J.LJ.LJLJ...
|
||||
The above sketch has many random bits of ground, some of which are in the loop (I) and some of which are outside it (O):
|
||||
|
||||
OF----7F7F7F7F-7OOOO
|
||||

|
||||
OOOOFJL-7O||O||||OOO
|
||||
OOOOL---JOLJOLJLJOOO
|
||||
In this larger example, 8 tiles are enclosed by the loop.
|
||||
|
||||
Any tile that isn't part of the main loop can count as being enclosed by the loop. Here's another example with many bits of junk pipe lying around that aren't connected to the main loop at all:
|
||||
|
||||

|

|

|

In this last example, 10 tiles are enclosed by the loop.

I implemented this task both in Python ang Go because brute-force solution was too slow in Python.
|
||||
|
||||
The code in both languages is very similar. But Go version solved the problem in 3 minutes and 24 seconds while Python version worked for as long as 5 hours 49 minutes 30 seconds. Both versions are single threaded.

--- Day 5: If You Give A Seed A Fertilizer ---
|
||||
You take the boat and find the gardener right where you were told he would be: managing a giant "garden" that looks more to you like a farm.
|
||||
|
||||
"A water source? Island Island is the water source!" You point out that Snow Island isn't receiving any water.
|
||||
|
||||
"Oh, we had to stop the water because we ran out of sand to filter it with! Can't make snow with dirty water. Don't worry, I'm sure we'll get more sand soon; we only turned off the water a few days... weeks... oh no." His face sinks into a look of horrified realization.
|
||||
|
||||
"I've been so busy making sure everyone here has food that I completely forgot to check why we stopped getting more sand! There's a ferry leaving soon that is headed over in that direction - it's much faster than your boat. Could you please go check it out?"
|
||||
|
||||
You barely have time to agree to this request when he brings up another. "While you wait for the ferry, maybe you can help us with our food production problem. The latest Island Island Almanac just arrived and we're having trouble making sense of it."
|
||||
|
||||
The almanac (your puzzle input) lists all of the seeds that need to be planted. It also lists what type of soil to use with each kind of seed, what type of fertilizer to use with each kind of soil, what type of water to use with each kind of fertilizer, and so on. Every type of seed, soil, fertilizer and so on is identified with a number, but numbers are reused by each category - that is, soil 123 and fertilizer 123 aren't necessarily related to each other.
|
||||
|
||||
For example:
|
||||
|
||||
seeds: 79 14 55 13
|
||||
|
||||
seed-to-soil map:
|
||||

|

|
||||
The almanac starts by listing which seeds need to be planted: seeds 79, 14, 55, and 13.
|
||||
|
||||
The rest of the almanac contains a list of maps which describe how to convert numbers from a source category into numbers in a destination category. That is, the section that starts with seed-to-soil map: describes how to convert a seed number (the source) to a soil number (the destination). This lets the gardener and his team know which soil to use with which seeds, which water to use with which fertilizer, and so on.
|
||||
|
||||
Rather than list every source number and its corresponding destination number one by one, the maps describe entire ranges of numbers that can be converted. Each line within a map contains three numbers: the destination range start, the source range start, and the range length.
|
||||
|
||||
Consider again the example seed-to-soil map:
|
||||
|
||||
50 98 2
|
||||
52 50 48
|
||||
The first line has a destination range start of 50, a source range start of 98, and a range length of 2. This line means that the source range starts at 98 and contains two values: 98 and 99. The destination range is the same length, but it starts at 50, so its two values are 50 and 51. With this information, you know that seed number 98 corresponds to soil number 50 and that seed number 99 corresponds to soil number 51.
|
||||
|
||||
The second line means that the source range starts at 50 and contains 48 values: 50, 51, ..., 96, 97. This corresponds to a destination range starting at 52 and also containing 48 values: 52, 53, ..., 98, 99. So, seed number 53 corresponds to soil number 55.
|
||||
|
||||
Any source numbers that aren't mapped correspond to the same destination number. So, seed number 10 corresponds to soil number 10.
|
||||
|
||||
So, the entire list of seed numbers and their corresponding soil numbers looks like this:
|
||||
|
||||
seed soil
|
||||
0 0
|
||||
1 1
|
||||
... ...
|
||||
48 48
|
||||
49 49
|
||||
50 52
|
||||
51 53
|
||||
... ...
|
||||
96 98
|
||||
97 99
|
||||
98 50
|
||||
99 51
|
||||
With this map, you can look up the soil number required for each initial seed number:
|
||||
|
||||
Seed number 79 corresponds to soil number 81.
|
||||
Seed number 14 corresponds to soil number 14.
|
||||
Seed number 55 corresponds to soil number 57.
|
||||
Seed number 13 corresponds to soil number 13.
|
||||
The gardener and his team want to get started as soon as possible, so they'd like to know the closest location that needs a seed. Using these maps, find the lowest location number that corresponds to any of the initial seeds. To do this, you'll need to convert each seed number through other categories until you can find its corresponding location number. In this example, the corresponding types are:
|
||||
|
||||
Seed 79, soil 81, fertilizer 81, water 81, light 74, temperature 78, humidity 78, location 82.
|
||||
Seed 14, soil 14, fertilizer 53, water 49, light 42, temperature 42, humidity 43, location 43.
|
||||
Seed 55, soil 57, fertilizer 57, water 53, light 46, temperature 82, humidity 82, location 86.
|
||||
Seed 13, soil 13, fertilizer 52, water 41, light 34, temperature 34, humidity 35, location 35.
|
||||
So, the lowest location number in this example is 35.
|
||||
|
||||
What is the lowest location number that corresponds to any of the initial seed numbers?
|
||||
|
||||
Your puzzle answer was 340994526.
|
||||
|
||||
The first half of this puzzle is complete! It provides one gold star: *
|
||||
|
||||
--- Part Two ---
|
||||
Everyone will starve if you only plant such a small number of seeds. Re-reading the almanac, it looks like the seeds: line actually describes ranges of seed numbers.
|
||||
|
||||
The values on the initial seeds: line come in pairs. Within each pair, the first value is the start of the range and the second value is the length of the range. So, in the first line of the example above:
|
||||
|
||||
seeds: 79 14 55 13
|
||||
This line describes two ranges of seed numbers to be planted in the garden. The first range starts with seed number 79 and contains 14 values: 79, 80, ..., 91, 92. The second range starts with seed number 55 and contains 13 values: 55, 56, ..., 66, 67.
|
||||
|
||||
Now, rather than considering four seed numbers, you need to consider a total of 27 seed numbers.
|
||||
|
||||
In the above example, the lowest location number can be obtained from seed number 82, which corresponds to soil 84, fertilizer 84, water 84, light 77, temperature 45, humidity 46, and location 46. So, the lowest location number is 46.
|
||||
|
||||
Consider all of the initial seed numbers listed in the ranges on the first line of the almanac. What is the lowest location number that corresponds to any of the initial seed numbers?
|
||||
|
||||
Your puzzle answer was 52210644.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **

--- Day 6: Wait For It ---
|
||||
The ferry quickly brings you across Island Island. After asking around, you discover that there is indeed normally a large pile of sand somewhere near here, but you don't see anything besides lots of water and the small island where the ferry has docked.
|
||||
|
||||
As you try to figure out what to do next, you notice a poster on a wall near the ferry dock. "Boat races! Open to the public! Grand prize is an all-expenses-paid trip to Desert Island!" That must be where the sand comes from! Best of all, the boat races are starting in just a few minutes.
|
||||
|
||||
You manage to sign up as a competitor in the boat races just in time. The organizer explains that it's not really a traditional race - instead, you will get a fixed amount of time during which your boat has to travel as far as it can, and you win if your boat goes the farthest.
|
||||
|
||||
As part of signing up, you get a sheet of paper (your puzzle input) that lists the time allowed for each race and also the best distance ever recorded in that race. To guarantee you win the grand prize, you need to make sure you go farther in each race than the current record holder.
|
||||
|
||||
The organizer brings you over to the area where the boat races are held. The boats are much smaller than you expected - they're actually toy boats, each with a big button on top. Holding down the button charges the boat, and releasing the button allows the boat to move. Boats move faster if their button was held longer, but time spent holding the button counts against the total race time. You can only hold the button at the start of the race, and boats don't move until the button is released.
|
||||
|
||||
For example:
|
||||
|
||||
Time: 7 15 30
|
||||
Distance: 9 40 200
|
||||
This document describes three races:
|
||||
|
||||
The first race lasts 7 milliseconds. The record distance in this race is 9 millimeters.
|
||||
The second race lasts 15 milliseconds. The record distance in this race is 40 millimeters.
|
||||
The third race lasts 30 milliseconds. The record distance in this race is 200 millimeters.
|
||||
Your toy boat has a starting speed of zero millimeters per millisecond. For each whole millisecond you spend at the beginning of the race holding down the button, the boat's speed increases by one millimeter per millisecond.
|
||||
|
||||
So, because the first race lasts 7 milliseconds, you only have a few options:
|
||||
|
||||
Don't hold the button at all (that is, hold it for 0 milliseconds) at the start of the race. The boat won't move; it will have traveled 0 millimeters by the end of the race.
|
||||
Hold the button for 1 millisecond at the start of the race. Then, the boat will travel at a speed of 1 millimeter per millisecond for 6 milliseconds, reaching a total distance traveled of 6 millimeters.
|
||||
Hold the button for 2 milliseconds, giving the boat a speed of 2 millimeters per millisecond. It will then get 5 milliseconds to move, reaching a total distance of 10 millimeters.
|
||||
Hold the button for 3 milliseconds. After its remaining 4 milliseconds of travel time, the boat will have gone 12 millimeters.
|
||||
Hold the button for 4 milliseconds. After its remaining 3 milliseconds of travel time, the boat will have gone 12 millimeters.
|
||||
Hold the button for 5 milliseconds, causing the boat to travel a total of 10 millimeters.
|
||||
Hold the button for 6 milliseconds, causing the boat to travel a total of 6 millimeters.
|
||||
Hold the button for 7 milliseconds. That's the entire duration of the race. You never let go of the button. The boat can't move until you let go of the button. Please make sure you let go of the button so the boat gets to move. 0 millimeters.
|
||||
Since the current record for this race is 9 millimeters, there are actually 4 different ways you could win: you could hold the button for 2, 3, 4, or 5 milliseconds at the start of the race.
|
||||
|
||||
In the second race, you could hold the button for at least 4 milliseconds and at most 11 milliseconds and beat the record, a total of 8 different ways to win.
|
||||
|
||||
In the third race, you could hold the button for at least 11 milliseconds and no more than 19 milliseconds and still beat the record, a total of 9 ways you could win.
|
||||
|
||||
To see how much margin of error you have, determine the number of ways you can beat the record in each race; in this example, if you multiply these values together, you get 288 (4 * 8 * 9).
|
||||
|
||||
Determine the number of ways you could beat the record in each race. What do you get if you multiply these numbers together?
|
||||
|
||||
Your puzzle answer was 275724.
|
||||
|
||||
The first half of this puzzle is complete! It provides one gold star: *
|
||||
|
||||
--- Part Two ---
|
||||
As the race is about to start, you realize the piece of paper with race times and record distances you got earlier actually just has very bad kerning. There's really only one race - ignore the spaces between the numbers on each line.
|
||||
|
||||
So, the example from before:
|
||||
|
||||
Time: 7 15 30
|
||||
Distance: 9 40 200
|
||||
...now instead means this:
|
||||
|
||||
Time: 71530
|
||||
Distance: 940200
|
||||
Now, you have to figure out how many ways there are to win this single race. In this example, the race lasts for 71530 milliseconds and the record distance you need to beat is 940200 millimeters. You could hold the button anywhere from 14 to 71516 milliseconds and beat the record, a total of 71503 ways!
|
||||
|
||||
How many ways can you beat the record in this one much longer race?
|
||||
|
||||
Your puzzle answer was 37286485.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **

--- Day 7: Camel Cards ---
|
||||
Your all-expenses-paid trip turns out to be a one-way, five-minute ride in an airship. (At least it's a cool airship!) It drops you off at the edge of a vast desert and descends back to Island Island.
|
||||
|
||||
"Did you bring the parts?"
|
||||
|
||||
You turn around to see an Elf completely covered in white clothing, wearing goggles, and riding a large camel.
|
||||
|
||||
"Did you bring the parts?" she asks again, louder this time. You aren't sure what parts she's looking for; you're here to figure out why the sand stopped.
|
||||
|
||||
"The parts! For the sand, yes! Come with me; I will show you." She beckons you onto the camel.
|
||||
|
||||
After riding a bit across the sands of Desert Island, you can see what look like very large rocks covering half of the horizon. The Elf explains that the rocks are all along the part of Desert Island that is directly above Island Island, making it hard to even get there. Normally, they use big machines to move the rocks and filter the sand, but the machines have broken down because Desert Island recently stopped receiving the parts they need to fix the machines.
|
||||
|
||||
You've already assumed it'll be your job to figure out why the parts stopped when she asks if you can help. You agree automatically.
|
||||
|
||||
Because the journey will take a few days, she offers to teach you the game of Camel Cards. Camel Cards is sort of similar to poker except it's designed to be easier to play while riding a camel.
|
||||
|
||||
In Camel Cards, you get a list of hands, and your goal is to order them based on the strength of each hand. A hand consists of five cards labeled one of A, K, Q, J, T, 9, 8, 7, 6, 5, 4, 3, or 2. The relative strength of each card follows this order, where A is the highest and 2 is the lowest.
|
||||
|
||||
Every hand is exactly one type. From strongest to weakest, they are:
|
||||
|
||||
Five of a kind, where all five cards have the same label: AAAAA
|
||||
Four of a kind, where four cards have the same label and one card has a different label: AA8AA
|
||||
Full house, where three cards have the same label, and the remaining two cards share a different label: 23332
|
||||
Three of a kind, where three cards have the same label, and the remaining two cards are each different from any other card in the hand: TTT98
|
||||
Two pair, where two cards share one label, two other cards share a second label, and the remaining card has a third label: 23432
|
||||
One pair, where two cards share one label, and the other three cards have a different label from the pair and each other: A23A4
|
||||
High card, where all cards' labels are distinct: 23456
|
||||
Hands are primarily ordered based on type; for example, every full house is stronger than any three of a kind.
|
||||
|
||||
If two hands have the same type, a second ordering rule takes effect. Start by comparing the first card in each hand. If these cards are different, the hand with the stronger first card is considered stronger. If the first card in each hand have the same label, however, then move on to considering the second card in each hand. If they differ, the hand with the higher second card wins; otherwise, continue with the third card in each hand, then the fourth, then the fifth.
|
||||
|
||||
So, 33332 and 2AAAA are both four of a kind hands, but 33332 is stronger because its first card is stronger. Similarly, 77888 and 77788 are both a full house, but 77888 is stronger because its third card is stronger (and both hands have the same first and second card).
|
||||
|
||||
To play Camel Cards, you are given a list of hands and their corresponding bid (your puzzle input). For example:
|
||||
|
||||
32T3K 765
|
||||
T55J5 684
|
||||
KK677 28
|
||||
KTJJT 220
|
||||
QQQJA 483
|
||||
This example shows five hands; each hand is followed by its bid amount. Each hand wins an amount equal to its bid multiplied by its rank, where the weakest hand gets rank 1, the second-weakest hand gets rank 2, and so on up to the strongest hand. Because there are five hands in this example, the strongest hand will have rank 5 and its bid will be multiplied by 5.
|
||||
|
||||
So, the first step is to put the hands in order of strength:
|
||||
|
||||
32T3K is the only one pair and the other hands are all a stronger type, so it gets rank 1.
|
||||
KK677 and KTJJT are both two pair. Their first cards both have the same label, but the second card of KK677 is stronger (K vs T), so KTJJT gets rank 2 and KK677 gets rank 3.
|
||||
T55J5 and QQQJA are both three of a kind. QQQJA has a stronger first card, so it gets rank 5 and T55J5 gets rank 4.
|
||||
Now, you can determine the total winnings of this set of hands by adding up the result of multiplying each hand's bid with its rank (765 * 1 + 220 * 2 + 28 * 3 + 684 * 4 + 483 * 5). So the total winnings in this example are 6440.
|
||||
|
||||
Find the rank of every hand in your set. What are the total winnings?
|
||||
|
||||
Your puzzle answer was 250254244.
|
||||
|
||||
The first half of this puzzle is complete! It provides one gold star: *
|
||||
|
||||
--- Part Two ---
|
||||
To make things a little more interesting, the Elf introduces one additional rule. Now, J cards are jokers - wildcards that can act like whatever card would make the hand the strongest type possible.
|
||||
|
||||
To balance this, J cards are now the weakest individual cards, weaker even than 2. The other cards stay in the same order: A, K, Q, T, 9, 8, 7, 6, 5, 4, 3, 2, J.
|
||||
|
||||
J cards can pretend to be whatever card is best for the purpose of determining hand type; for example, QJJQ2 is now considered four of a kind. However, for the purpose of breaking ties between two hands of the same type, J is always treated as J, not the card it's pretending to be: JKKK2 is weaker than QQQQ2 because J is weaker than Q.
|
||||
|
||||
Now, the above example goes very differently:
|
||||
|
||||
32T3K 765
|
||||
T55J5 684
|
||||
KK677 28
|
||||
KTJJT 220
|
||||
QQQJA 483
|
||||
32T3K is still the only one pair; it doesn't contain any jokers, so its strength doesn't increase.
|
||||
KK677 is now the only two pair, making it the second-weakest hand.
|
||||
T55J5, KTJJT, and QQQJA are now all four of a kind! T55J5 gets rank 3, QQQJA gets rank 4, and KTJJT gets rank 5.
|
||||
With the new joker rule, the total winnings in this example are 5905.
|
||||
|
||||
Using the new joker rule, find the rank of every hand in your set. What are the new total winnings?

--- Day 8: Haunted Wasteland ---
|
||||
You're still riding a camel across Desert Island when you spot a sandstorm quickly approaching. When you turn to warn the Elf, she disappears before your eyes! To be fair, she had just finished warning you about ghosts a few minutes ago.
|
||||
|
||||
One of the camel's pouches is labeled "maps" - sure enough, it's full of documents (your puzzle input) about how to navigate the desert. At least, you're pretty sure that's what they are; one of the documents contains a list of left/right instructions, and the rest of the documents seem to describe some kind of network of labeled nodes.
|
||||
|
||||
It seems like you're meant to use the left/right instructions to navigate the network. Perhaps if you have the camel follow the same instructions, you can escape the haunted wasteland!
|
||||
|
||||
After examining the maps for a bit, two nodes stick out: AAA and ZZZ. You feel like AAA is where you are now, and you have to follow the left/right instructions until you reach ZZZ.
|
||||
|
||||
This format defines each node of the network individually. For example:
|
||||
|
||||
RL
|
||||
|
||||
AAA = (BBB, CCC)
|
||||
BBB = (DDD, EEE)
|
||||
CCC = (ZZZ, GGG)
|
||||
DDD = (DDD, DDD)
|
||||
EEE = (EEE, EEE)
|
||||
GGG = (GGG, GGG)
|
||||
ZZZ = (ZZZ, ZZZ)
|
||||
Starting with AAA, you need to look up the next element based on the next left/right instruction in your input. In this example, start with AAA and go right (R) by choosing the right element of AAA, CCC. Then, L means to choose the left element of CCC, ZZZ. By following the left/right instructions, you reach ZZZ in 2 steps.
|
||||
|
||||
Of course, you might not find ZZZ right away. If you run out of left/right instructions, repeat the whole sequence of instructions as necessary: RL really means RLRLRLRLRLRLRLRL... and so on. For example, here is a situation that takes 6 steps to reach ZZZ:
|
||||
|
||||
LLR
|
||||
|
||||
AAA = (BBB, BBB)
|
||||
BBB = (AAA, ZZZ)
|
||||
ZZZ = (ZZZ, ZZZ)
|
||||
Starting at AAA, follow the left/right instructions. How many steps are required to reach ZZZ?
|
||||
|
||||
Your puzzle answer was 18157.
|
||||
|
||||
The first half of this puzzle is complete! It provides one gold star: *
|
||||
|
||||
--- Part Two ---
|
||||
The sandstorm is upon you and you aren't any closer to escaping the wasteland. You had the camel follow the instructions, but you've barely left your starting position. It's going to take significantly more steps to escape!
|
||||
|
||||
What if the map isn't for people - what if the map is for ghosts? Are ghosts even bound by the laws of spacetime? Only one way to find out.
|
||||
|
||||
After examining the maps a bit longer, your attention is drawn to a curious fact: the number of nodes with names ending in A is equal to the number ending in Z! If you were a ghost, you'd probably just start at every node that ends with A and follow all of the paths at the same time until they all simultaneously end up at nodes that end with Z.
|
||||
|
||||
For example:
|
||||
|
||||
LR
|
||||
|
||||
11A = (11B, XXX)
|
||||
11B = (XXX, 11Z)
|
||||
11Z = (11B, XXX)
|
||||
22A = (22B, XXX)
|
||||
22B = (22C, 22C)
|
||||
22C = (22Z, 22Z)
|
||||
22Z = (22B, 22B)
|
||||
XXX = (XXX, XXX)
|
||||
Here, there are two starting nodes, 11A and 22A (because they both end with A). As you follow each left/right instruction, use that instruction to simultaneously navigate away from both nodes you're currently on. Repeat this process until all of the nodes you're currently on end with Z. (If only some of the nodes you're on end with Z, they act like any other node and you continue as normal.) In this example, you would proceed as follows:
|
||||
|
||||
Step 0: You are at 11A and 22A.
|
||||
Step 1: You choose all of the left paths, leading you to 11B and 22B.
|
||||
Step 2: You choose all of the right paths, leading you to 11Z and 22C.
|
||||
Step 3: You choose all of the left paths, leading you to 11B and 22Z.
|
||||
Step 4: You choose all of the right paths, leading you to 11Z and 22B.
|
||||
Step 5: You choose all of the left paths, leading you to 11B and 22C.
|
||||
Step 6: You choose all of the right paths, leading you to 11Z and 22Z.
|
||||
So, in this example, you end up entirely on nodes that end in Z after 6 steps.
|
||||
|
||||
Simultaneously start on every node that ends with A. How many steps does it take before you're only on nodes that end with Z?

--- Day 9: Mirage Maintenance ---
|
||||
You ride the camel through the sandstorm and stop where the ghost's maps told you to stop. The sandstorm subsequently subsides, somehow seeing you standing at an oasis!
|
||||
|
||||
The camel goes to get some water and you stretch your neck. As you look up, you discover what must be yet another giant floating island, this one made of metal! That must be where the parts to fix the sand machines come from.
|
||||
|
||||
There's even a hang glider partially buried in the sand here; once the sun rises and heats up the sand, you might be able to use the glider and the hot air to get all the way up to the metal island!
|
||||
|
||||
While you wait for the sun to rise, you admire the oasis hidden here in the middle of Desert Island. It must have a delicate ecosystem; you might as well take some ecological readings while you wait. Maybe you can report any environmental instabilities you find to someone so the oasis can be around for the next sandstorm-worn traveler.
|
||||
|
||||
You pull out your handy Oasis And Sand Instability Sensor and analyze your surroundings. The OASIS produces a report of many values and how they are changing over time (your puzzle input). Each line in the report contains the history of a single value. For example:
|
||||
|
||||
0 3 6 9 12 15
|
||||
1 3 6 10 15 21
|
||||
10 13 16 21 30 45
|
||||
To best protect the oasis, your environmental report should include a prediction of the next value in each history. To do this, start by making a new sequence from the difference at each step of your history. If that sequence is not all zeroes, repeat this process, using the sequence you just generated as the input sequence. Once all of the values in your latest sequence are zeroes, you can extrapolate what the next value of the original history should be.
|
||||
|
||||
In the above dataset, the first history is 0 3 6 9 12 15. Because the values increase by 3 each step, the first sequence of differences that you generate will be 3 3 3 3 3. Note that this sequence has one fewer value than the input sequence because at each step it considers two numbers from the input. Since these values aren't all zero, repeat the process: the values differ by 0 at each step, so the next sequence is 0 0 0 0. This means you have enough information to extrapolate the history! Visually, these sequences can be arranged like this:
|
||||
|
||||
0 3 6 9 12 15
|
||||
3 3 3 3 3
|
||||
0 0 0 0
|
||||
To extrapolate, start by adding a new zero to the end of your list of zeroes; because the zeroes represent differences between the two values above them, this also means there is now a placeholder in every sequence above it:
|
||||
|
||||
0 3 6 9 12 15 B
|
||||
3 3 3 3 3 A
|
||||
0 0 0 0 0
|
||||
You can then start filling in placeholders from the bottom up. A needs to be the result of increasing 3 (the value to its left) by 0 (the value below it); this means A must be 3:
|
||||
|
||||
0 3 6 9 12 15 B
|
||||
3 3 3 3 3 3
|
||||
0 0 0 0 0
|
||||
Finally, you can fill in B, which needs to be the result of increasing 15 (the value to its left) by 3 (the value below it), or 18:
|
||||
|
||||
0 3 6 9 12 15 18
|
||||
3 3 3 3 3 3
|
||||
0 0 0 0 0
|
||||
So, the next value of the first history is 18.
|
||||
|
||||
Finding all-zero differences for the second history requires an additional sequence:
|
||||
|
||||
1 3 6 10 15 21
|
||||
2 3 4 5 6
|
||||
1 1 1 1
|
||||
0 0 0
|
||||
Then, following the same process as before, work out the next value in each sequence from the bottom up:
|
||||
|
||||
1 3 6 10 15 21 28
|
||||
2 3 4 5 6 7
|
||||
1 1 1 1 1
|
||||
0 0 0 0
|
||||
So, the next value of the second history is 28.
|
||||
|
||||
The third history requires even more sequences, but its next value can be found the same way:
|
||||
|
||||
10 13 16 21 30 45 68
|
||||
3 3 5 9 15 23
|
||||
0 2 4 6 8
|
||||
2 2 2 2
|
||||
0 0 0
|
||||
So, the next value of the third history is 68.
|
||||
|
||||
If you find the next value for each history in this example and add them together, you get 114.
|
||||
|
||||
Analyze your OASIS report and extrapolate the next value for each history. What is the sum of these extrapolated values?

--- Part Two ---
|
||||
Of course, it would be nice to have even more history included in your report. Surely it's safe to just extrapolate backwards as well, right?
|
||||
|
||||
For each history, repeat the process of finding differences until the sequence of differences is entirely zero. Then, rather than adding a zero to the end and filling in the next values of each previous sequence, you should instead add a zero to the beginning of your sequence of zeroes, then fill in new first values for each previous sequence.
|
||||
|
||||
In particular, here is what the third example history looks like when extrapolating back in time:
|
||||
|
||||
5 10 13 16 21 30 45
|
||||
5 3 3 5 9 15
|
||||
-2 0 2 4 6
|
||||
2 2 2 2
|
||||
0 0 0
|
||||
Adding the new values on the left side of each sequence from bottom to top eventually reveals the new left-most history value: 5.
|
||||
|
||||
Doing this for the remaining example data above results in previous values of -3 for the first history and 0 for the second history. Adding all three new values together produces 2.
|
||||
|
||||
Analyze your OASIS report again, this time extrapolating the previous value for each history. What is the sum of these extrapolated values?
