solved the first day 🎄 ✨
ok ok, this was a mindf*ck, the 1st day of advent of code 2025... need a break 🧠

but it's there, and under the 100 lines of code, also purely functional style, no mutations 🫧

done in Lisp (Guile Scheme)
it's also quite fast (much faster than my first naive list shifting idea)

hope I manage to solve ALL the challenges 😃
