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

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

Full code at GitHub.

Edit: you don't need to determine the type of hand, but you can directly compare the card counts. Second version @GitHub.

New version @GitHub.

So, a new version with a lot less almost-duplicate code @GitHub.

Completed part 2, see GitHub. I couldn't really use the same `DiracDice` class and simply use another `Die`, but had to create a separate `DiracDice2` class.Basically, just keep track of the possible universe state and their counts, and try all possible combinations of die rolls. Keep playing until all universes have a winner.

Raku, see GitHub.

The rest is the same as my first attempt, but full code at GitHub.
