Advent of Code 2025

I’m doing Advent of Code again. My answers thus far are on GitHub. I’m aiming for algorithms with worst case time complexity \(\mathcal{O}(\textit{finishes by Christmas})\).

Advent of Code 2024

I’m doing Advent of Code again. My answers thus far are on GitHub.

This year, I vow to stop when it takes up too much time… Last time I tried (2022) over here. It will be interesting to see if I can reuse any code or ideas.

Advent of Code is “an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.”

Here are my solutions, using R (obvs): GitHub repo.
