Wow, so you never had to write complete programs for assignments? That "write a sort function" question seems more suitable to what I'd expect on an exam. You find out who knows/doesn't know a lot faster than a homework problem where you may be able to program it at the time but don't understand in general only to fail on the next exam, or maybe you think you know it already so you just copy from somewhere and change variables, but don't really know it, and so you also fail at test time.

Bleh. The whole point of catching plagiarizers has been to determine whether work was done in some expected way, not to make sure learning happened or anything useful came from the work.
