[ SmokeDetector | MS ] Blacklisted user (71): Bound the Euclidean distance between two points on a cone by Guangyang_ZJU on math.SE

@Jack You and darij and a couple of others recently undeleted this, even though it is a PSQ (as I said sample test case does not count as context/effort).

I can't be bothered to search to find out where the PSQ you deleted came from, but it is obviously some contest problem.

Likely, it was another cheating attempt. Just because we don't know for sure whether it is does not imply that it isn't.
