Problem Statement
You have a grid. A "move" on the grid consists of moving squares to the right and squares down. In case of exiting by a line, it continues at the beginning (left) of the same line and in case of ending a column, it continues at the beginning of the same column (above). Where should we start so that after moves we end up in a corner?
