  Advent of Code (by morgoth1145)

Hm, thinking about it I think I actually have something coded up in my lib.math module which would apply here. Take a look at chinese_remainder_incongruence or offset_chinese_remainder_incongruence (which delegates to the former but accepts a slightly different set of expressions that make more sense in my head.) Obviously converting the cycles to all the incongruencies is absurd, but the first step in my algorithm is converting to candidate valid congruencies which does match this problem well.

Sorry for the late response. The key is to also use await on the first part. I created a gist so you can have a look. The bench function I wrote is here in case you need it.

  Advents of Code in NASM x86_64 assembly (by JustinHuPrime)

Part 1 was implemented pretty much following the problem statement - I chose to represent the map using a dense data structure (since, after all, RAM is cheap enough that I can ask for 26^3 * 4 bytes (~70kib) just because). I parsed the instructions and the map, but I found I couldn't zero-terminate my instructions, since I was representing left as zero and right as two (since these were actually memory offsets). I thus used 0xff - something the fullptr folks might appreciate. The map was parsed as follows - I treated each node as a base26 integer, where the first is an index into an array of pairs of words, and each word is the index that the left and right nodes lead to.

  For the sixth time trying to see if I remember something (by Leftfish)

You know what? Getting my rear kicked every year since 2018 pays off. I may have given up on day 15 of AoC 2019, but I did learn something. That's why about 10 minutes into my naive approach's fantastillion iteration, I recalled the Jupiter moons puzzle. As soon as I saw that this approach would work for the test data, it felt good. So to solve part 2, I just needed to look up a nice lcm-of-a-list formula.

• aoc

Had some fun with the fact that the input is valid Python syntax, which in turn only made part 2 more tedious and the whole thing harder to debug.

  Advent of Code (by MichaelBrunn3r)

[LANGUAGE: Rust]I was running in circles trying to solve this one.First part was easy enough. I was running into an infinite loop in part 2 and then sadly was spoilered the LCM solution. At least I head fun optimizing the code :)Part 2: I converted the 3 char node names into u16 keys. I store the keys of the left/right successors of each node in a massive array, which I can simply index with they node keys. This proved significantly faster than a HashMap. While converting lines into nodes, I store all keys of nodes ending in an A in a starting nodes array. Next, I calcualte the cycle length for each starting row and then calculating the common LCM. I used rayon to speed things up with multithreading (minor improvement)[Code]

  My solutions to the Advent of Code event (by Robin270)

This was a tricky one, but I managed to solve it in an effective way (the lcm method). As always you can see it on my GitHub.

https://github.com/carl-omniart/advent_of_code/tree/main/2023 For part two, I defined a class that, in my head, was a cross of a Set and an Enumerator. This class took the offset (span of steps prior to a repetition), the period (span of repeated steps), and the points (steps that reached a location ending in Z). Knowing the pattern, an instance of this class quickly enumerates all the Z-ending steps between any span of steps. Instances of this class can be combined. The new offset is the greater of the two offsets; the new period is the lowest common multiple of the two periods. To get the new set of points, I used one instance to enumerate the points over the span of the new first period and checked to see if the other instance included them. The instance doing the enumerating was always the one in which the points were more spread out. (If you were trying to find a common multiple between 3 and 5167, you'd rather enumerate 5167 three times than three 5167 times.) I combined the various ghost paths and found the first point. P.S. I named this class Syzygy, which is a term for an astronomical conjunction and a title of an X-Files episode that features a young Jack Black. Doesn't exactly make sense as a class name here but what the heck.

Got the answer for Part 2 by doing prime factorization, but later rewrote with lcm

Part 1 is pretty trash, but part 2 works great using lcm
