This sounds like the "coding for engineers" course I was a TA of. Everybody copied everybodies code and depending on their effort they either modified the variable names, flow or nothing (including the original authors name).

Long story short: asking them to make small changes and then tell us what would happen was a shurefire way to detect the true cheaters and not the lazy people.

I also fondly remember triggering float errors in loops so you'd get an extra cycle due to it ending in .999etc instead of 0.
