==Problem Statement== You are given a map of a rectangular grid with N rows and M columns. Each cell of the grid is either empty or contains an obstacle. You are standing in the upper-left corner of the grid at the coordinates (1,1). You can move one step at a time in any of the four cardinal directions (up, down, left, or right). You cannot move outside the boundaries of the grid or onto cells containing obstacles. Your goal is to determine your current position in the grid.
