What I find strange about this test is that it also weeds out 99.5% of candidates who can't seem to google for "programming interview" before turning up at one! Amazing how many (3rd year Comp Sci) students have never heard of it.

Thing is, I graduated CS without ever hearing about this, but that doesn't make it any less trivial. The amount of HN articles on this question makes me feel like I'm missing some huge "gotcha" secret about the answer.
