My cynicism (not contempt - I know that the students are under various sorts of pressures) stems from personal experience. It's not much good explaining how simple it is to understand the xor-swap - it doesn't change the fact that the majority of engineering students go to the link like the one I posted, compile a list of questions and answers, and rattle off answers before the question is even completed in the interviews. It's like knowing [any interesting method] can be used to accomplish a task, without knowing why said method works. edit: I realise all this is OT, but I was downvoted for my earlier post and felt the need to defend it.
