I finished the Advent of Code 2023 challenges.

It’s the first time I participate. It took quite some time but it was fun and I learned quite a bit. Maybe my programs are not too efficient nor the solutions too clever, but it was fun to figure them out all before checking the solutions of other’s. My analysis of the problems is here. For the analysis of each day’s problems:
