PrepBuddy and Rahul both are fascinated by Virtual reality. PrepBuddy is a VR Game designer and decided to create a puzzle game for his friend Rahul. Rahul will be able to play this game using a VR headset. In the game, PrepBuddy created a rectangular $n*m$ maze. The squares have coordinates $(x, y) (1 ≤ x ≤ n, 1 ≤ y ≤ m)$, where $x$ is the index of the row and $y$ is the index of the column.
