  • Did some nice Python OOP! Split into three files, part 1, part 2, and shared classes.

  • As a side note, I took inspiration from a post the other day about adding AoC badges to your repository README file. I use GitLab, which lets you define badges as properties of your repository. So I added badges to my repository's header area, driven by a JSON file in the repository. The JSON file is updated manually by a script. (I might add some automated updates at some point, but manual works okay for now.)

  • This one kicked my ass for a while, which was confusing because the tests all passed fine with example data. Eventually I tracked down the problem to the way I was reading in the actual puzzle input... I should've known.
