I just completed all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com/

Part 2 of days 9 and 10 nearly broke me, and I had to rely on 3rd party libraries to get them done. Ray casting and solving simultaneous equations in code ain't my thing.

But overall, it was so much fun! 😀

A lucky guess led inevitably to an answer I'd otherwise probably not have found. I'm pretty sure I've never used that word in writing before!

I just completed "Reactor" - Day 11 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/11

Part 2 of Days 9 and 10 remain incomplete! Both require some really clever optimisation I haven't cracked yet. So did this one, but I got it. 😀

I just completed "Laboratories" - Day 7 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/7

So my first solution to part 2 would probably take the lifetime of the universe to run. I heavily optimised it, but still took way too long. Then I cached results, and it's less than a second. 😀

I've completed "Trash Compactor" - Day 6 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/6

Part 2 was particularly clever, and very fun to do.

I've completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/5

Part 1 was easy, but part 2 drove me nuts! Glad it's done.
