As a warmup for this year’s Advent of Code, I’m re-reading and posting my solutions to last year’s challenges. You can read, run and edit today’s solution by following the post link.

Today started quite easily: build a map and then follow some directions to navigate around it. Part 2? The map is now wrapped around a cube. Oof. I dealt with it by setting up logic for an “ideal” cube layout, and then mapping the provided definition onto that. Oddly, my solution for part2 seems to run faster than part1 despite all the added complexity…
