A word of warning

If you really want to learn Pascal and improve through the challenges, don't just copy my solutions. You won't learn anything that way! (Cheating and plagiarizing is not permitted on the Codewars website. Violators will face account suspension or ban.)

My solutions to some Codewars challenges, programmed in Pascal, might not be the most sophisticated, but at least mostly easy to read and understand.

Current Pascal rank (since March 31, 2026): 4 kyu.
