but that one should be, in fact, well known. i've been out of school forever but surely it has to be taught now?

so, this question isn't testing if you can find a loop, it's testing whether you have enough experience to have heard of it. which is a fine enough thing to test for.

i understand your point, that questions are often designed poorly, but your example isn't necessarily a good one.
