🎄 Advent of Code 2025 🎄

My solutions for the Advent of Code 2025 programming puzzles. Like last year I'll probably use Picat for most of these with Nim as a fallback for graph search problems that can be expensive in Picat.

Previous challenges

  • 2015 (working on these now in Picat)
  • 2019 (my first AoC, unfinished, to be resumed / restarted later...)
  • 2020 (mostly Haskell, one or two in Rust, Python and zz)
  • 2021 (mostly Haskell, with one in the magical Picat)
  • 2022 (mostly Nim)
  • 2023 (mostly Picat)
  • 2024 (mostly Picat)
