Anyone tried leetcode with lisp? I'm not sure if its a good way to learn or an exercise in banging your head against the wall.

I really enjoy solving project euler puzzles with CL. It's very well suited to them.

I've toyed around with some similar sites in the past. Challenges like that that sit closer to purer algorithm tasks are not at all hard in Common Lisp.

Advent of Code is pretty good with CL.
