This is a thread to discuss solutions to Advent of Code 2025. As mentioned in

viewtopic.php?p=2347868#p2347868

there will only be twelve puzzles to pass the time until Christmas this year. That is good because other years I nearly missed Christmas on account of still working the puzzles.

Speaking of missing things, that Raspberry Pi 5 from last Christmas is still not a NAS and I just missed a sale for 24 TB hard disks. Fortunately, that Pi 5 is currently nailed to a piece of wood, running off the Pi 4 power supply and ready for the code produced by Scratchy, Purr, Shy and myself.

I'll miss Fido this year.

Is anyone else planning to do Advent of Code with a Raspberry Pi this year?
