Here's how I asked the question. I would present the data for a 2 node cycle and ask what would happen to this routine. Here's a response I would get far too often: A conditional clause detecting a 2 node cycle. Then I would present a 3 node cycle, then ask how to detect an n node cycle, period.

Lots of 3.5+ GPA grads can't make that logical leap!
