Trying to do all days in whatever language I feel like doing - happy holidays!
nix develop . # enter dev shell, run day of your choice in one of the lang dirs [rs, prolog]You might say I do not have nix, then either ignore it or install:
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
