advent-of-code VS advent-of-code-kotlin

I just did simple BFS on the lava cubes for part 1. For part 2, I just did a BFS on the bounding cube. Total runtime - 500 micro seconds for both parts on my 8 years old laptop: https://github.com/SvetlinZarev/advent-of-code/blob/main/2022/aoc-day-18/src/lib.rs

My solution is pretty simple - top down DP. On each step we can do only one of two things: * open a valve and stay in current position * do not open a vale, but move to a different positions

Here are the results of my benchmarks, which you can also run

You can calculate the distances between the points found by each scanner. If two scanners report points with the same distance between them, then most probably they are adjacent. Runs in 4ms on my machine: https://github.com/SvetlinZarev/advent-of-code/tree/main/2021/aoc-day-19

You can copy the release profile from here https://github.com/SvetlinZarev/advent-of-code/blob/main/2021/aoc-day-25/Cargo.toml#L8 and copy that directory to enable compilation for the machine's cpu https://github.com/SvetlinZarev/advent-of-code/tree/main/2021/aoc-day-25/.cargo

I want to share my repo for whoever is interested. It contains Rust solutions for:

Mine (rust)runs for 50ms for both parts. I've used just a regular bruteforce approach, so nothing fancy. There are several things I did that reduced the execution time:

Kotlin solution (part 1 and part 2 merged)

Kotlin solution, probably not the most efficient but does the job.

Kotlin solution for day 7, can be done fairly concisely:

Kotlin solution using a fish counter map:

Day 3 — a few key concepts used are: extensions for example on List type higher-order functions aka a function which takes other functions as parameters

Nice! here is my solution also in Kotlin

Kotlin solution for day 3, not the most concise nor most optimized but gets the job done and fairly readable.

Kotlin, solution for part 1 and 2 — not super concise but a few cool concepts if you're learning the language.

You can find the source code for my solution here.
