Unfortunately for him, the same activity is also taken up by a few flies that have landed on his window and are looking into the distance. Marin immediately hurried to get his square racket for killing flies. At the same time, he wondered how many flies it is possible to kill in one shot. After trying to scare away the flies unsuccessfully for a few hours, he decided to ask for your help. Marin has sent you a picture of his window, the dimensions being R x S pixels and has also told you the length of the side of the racket he uses to kill the flies, in pixels. Your task is to determine the maximal amount of flies that Marin could have killed in a single shot and mark one such shot in the picture.
