EWCO (Esolang Wiki Code Olympiad) is a programming challenge created by User:LEOMOK created in May 2025. Every two months, a new challenge is created. Anyone can solve each challenge, and there is no time limit for any of them. You can put your solutions, partial answers or findings in the talk page. Once you are confident you have a full solution, you can write it on the talk page of the corresponding challenge page.
