Finally got around to doing Day 4. That was fun. I'm really happy my decision to completely overengineer my Part 1 solution meant that Part 2 took all of minute to code.

@MBraedley is slacking!

@Wipqozn Yeah, I'm working on today's I spent a little while trying to figure out if there was a more intelligent way of doing it than just tracking all the boards

My problem with Day 4 was not realizing they didn't count diagonals.

@Batophobia Oof

That would make things a lot more difficult

I specifically checked the puzzle for that lol

My Day 4 solutions had some cool uses of numpy, imo

Here's my aoc2021 repo, if anyone's interested: github.com/SaintWacko/aoc2021
