Advent of Code 2025

Programming
1

Hi all,

It’s getting to be that time of year again where we can neglect our work, families, and friends to solve a tricky programming puzzle every day! :snowman:

If you haven’t heard, this year there will only be 12 days of AoC instead of the usual 25.

So, whether you’re trying out a new programming language or just want to brush up on some algorithm practice, let’s try to motivate each other and learn something new. Hopefully, having less puzzles to complete will give you more reason to join this year and push to the end!..Unless it gets hard by day 3 and we are all crying.

Last year was good fun, I’m looking forward to doing this again. Haven’t decided if I’ll use CL like last year or something else, though.
