Whiteboard Interview Questions
I teach a software engineering lab class for Seniors in Computer Science and Engineering (Bachelor's degree). I understand that many companies have interviewees solve simple programming problems on a whiteboard or piece of paper.

I would like to prepare my students for this as they do not normally have to stand in front of a judgmental audience and write programs on a whiteboard. Thus, I am looking for some good questions to ask them.

The question should be answerable in 15-30 minutes, on a whiteboard, by a solid CSE graduate. I am looking for programming questions, not puzzles.
