Advent of Code 2025

I'm really excited for Advent of Code 2025. Specifically the changes which have been made to the format. Fewer puzzles means I'll actually be able to complete it this year instead of losing interest when it becomes too hard to complete a puzzle on a busy evening. No leaderboard means I'll give my variables sensible names instead of stuff like sm, data1, a and my personal favorite, b.

Here are my solutions with a little bit of writing about them. Using cool new subpages!

I'll add these as I do them 👏👏
