Write a recursive method named escapeMaze that uses recursive backtracking to find a pathway out of a 2-dimensional maze. Assume that the maze is represented as an object of class Maze which is provided to you. A Maze object stores its data internally as a 2-dimensional array of char values, where row 0 is the top and column 0 is the left edge. A maze contains walls and empty squares. Empty squares are represented as the space character ' ', and any other character is considered a wall. Your method should accept three parameters: a maze and a starting row/column from which to begin your search. You are to explore the various ways to move up, down, left and right in the maze to try to reach an open spot on the outer border of the maze (which would be an exit from the maze).
