I've completed this year's #AdventofCode #AoC2025!
Huge thanks to @was.tl for such an engaging challenge. This is my first time solving every problem, although I did get some help for the last couple of days.
I'm excited to build on what I've learned for next year's challenges!

Well, today's #adventofcode puzzle was fairly great. Perl did complain a bit about deep recursion, though. It does have a good reason to complain, but in the end it did the job.
"You don't have enough stars to finish decorating the North Pole, though. You need 2 more."
Bah.

L'Advent of Code continue cette semaine, donc je continue à résoudre les énigmes en direct. Certains jours j'aurai des gens pour m'aider.
Vu que c'est la dernière semaine cette année, il faut s'attendre à ce que ça se corse un peu plus.

When removing debugging output I had removed one line too many, so it didn't actually exclude the things it should exclude. Now it does, and finishes in 20 minutes, but the answer is wrong (it is right for the sample input, interestingly). Weird.
