> someone who can't discover the tortoise and hare algorithm on their own probably shouldn't have a computer science degree This sentence is simply ridiculous. Most engineers aren't able to discover this trick. I wouldn't. The same goes for the rod cutting problem or the maximum sub-array problem (Kadane algorithm): expecting an engineer to find them, especially in an interview, is totally inane.
