Advent of Code 🎄 | December 🎁 Monthly Challenge

[Wertzui123]

Just 24 more days until Christmas! 🧑‍🎄
While you're waiting, you might want to check out Advent of Code - an "Advent calendar of small programming puzzles for a variety of skill levels". Not only is it a great way to test and improve your coding skills, but it is also December's monthly challenge! 👾

I've set up a private leaderboard for everyone who wants to participate in AoC with ASPL. You can join it at https://adventofcode.com/2025/leaderboard/private by entering the code 1109872-10fb7841.

AoC lets you be part of multiple leaderboards and solve the puzzles in any language you like. So the only rule for the ASPL leaderboard is: complete the challenges with an ASPL program, even if you've already solved them in another language. ⚙️

As always, the winner of the monthly challenge - this time determined using the leaderboard and not by a poll - will receive a certificate, a book voucher, and a shoutout on BlueSky and X. 🏆

I wish everyone good luck in AoC and a merry Christmas season! 💖
