Advent of Code 2022

These are my solutions to the Advent of Code 2022 puzzles. These solutions aren't great, but they're mine, so that's something.

These are starting out in Rust, because I'm not very good at Rust.

Getting Started

cargo run -rq [day] [puzzle] [type]

[day] is one of day-1 | day-2 | ...
[puzzle] is one of puzzle-1 | puzzle-2
[type] is one of sample | puzzle, where sample runs with the sample input, and puzzle runs with the puzzle input

Development

If doing development, ensure the git hooks are set:

ln -s $(readlink -f .hooks/pre-push) .git/hooks/pre-push

Notes

Day 8, Puzzle 2: I'm not thrilled with the quality of this. There's a lot of copy and paste code, feels like it could be a lot cleaner.
