advent of code

This was my fourth year doing Advent of Code, my second year trying to compete, and my first year appearing on the top 100 leaderboard (if only for a single day). Last year lit a fire in me to become faster, and since then I have built my programming language Zote, practiced some competitive programming, and learned to touch type using Colemak. This will be a short retrospective on this year's event, as well as my preparation leading up to it.
