Solutions to the Protohackers challenges in Common Lisp.

I'm just learning, if you want well-written and commented code by an expert lisp hacker then read PAIP, not this.

You can download all dependencies and run any challenge with guix, for example:

guix shell -L extra-packages/ -m manifest.scm  -- sbcl --load protohackers.asd --eval "(require :protohackers)" --load challenge0.lisp
