Can you teach using git repositories? Have them commit in a way that shows their understanding at each point as they incrementally improve or solve the problem. Have them split into groups and submit MR's to each other. Give them them ability to tag other. Have them upload their MR to a system with CI and check that it passes tests, lint, style etc. If the commits are broadly similar then likely they did the same process as most of the class, if the commits are much different then check their understanding and/or cheating.
