advent-of-code-2021 VS adventlang

Some very interesting advent of code contributions written in Rust, available on github, use bitwise operations. Shout out to Tim Visee! https://github.com/timvisee/advent-of-code-2021/blob/master/...

This may be the closest thing I've personally seen: https://github.com/timvisee/advent-of-code-2021

Part 1 1.05ms

The orientation calculation could be done by matrix indexes operations https://github.com/FlakM/aoc2021/blob/main/day5/task1/src/main.rs and then its easier to create ranges. You can also use some clever crates and get some calculations for free https://github.com/timvisee/advent-of-code-2021/blob/master/day05b/src/main.rs

Some create a language just for AoC, for example: https://github.com/healeycodes/adventlang
