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/...

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

Fun one :D

Way trickier than I was expecting

:D

Classic LCM

Who wants spaghetti?

Much easier than yesterday's :D

Messy. Thankfully got part two pretty quickly recognizing that we can mod the worry level by the product of the test integers. Might refactor / clean this up tomorrow morning

Impressive how fast everyone was with this one today
