Added attribution. This contest’s submission deadline has passed. Added to review
Jan 5 at 13:22 comment added Stiv @Toffee As was I - a keen-eyed user mentioned it in chat... I wouldn't delete right now - the contest has closed, we spotted it too late. If the mods think further action is required, they can arrange whatever deletions are necessary. You answered in good faith (it was a good-looking puzzle, I wouldn't have spotted the original source without prompting).
Jan 5 at 10:53 comment added Toffee @Stiv I was unaware of this tournament. Should I delete my answer?

Jan 5 at 0:15 comment added Stiv This was a problem in the recent round of USAMTS problems that closed just yesterday. Posting this here clearly violates the terms of the contest: "Participants may not discuss the problems with others before the deadline for solution submission." You are also posting past USAMTS problems without attribution, giving the impression they are your own. Please desist.
