Friday Puzzles #111
So I completely forgot about this puzzle, which I wrote in a half an hour spell on the train on Friday. My apologies for its rather late appearance. Anyway, there isn’t so much to this puzzle, except for one little cute trick, which was enough to save this from the unpublished pile. Enjoy!
