Is cheese reachable in the maze?

Mooshak the mouse has been placed in a maze.There is a huge chunk of cheese somewhere in the maze.
The maze is represented as a two-dimensional array of integers, where o represents walls, 1 represents paths where Mooshak can move, and 9 represents the huge chunk of cheese.Mooshak starts in the top-left corner at 0,0.

Write a method isPath of class Maze Path to determine if Mooshak can reach the huge chunk of cheese. The input to isPath consists of a two dimensional array grid for the maze matrix.

The method should return 1 if there is a path from Mooshak to the cheese, and 0 if not.
Mooshak is not allowed to leave the maze or climb on walls/

Example 8x8 maze where Mooshak can get the cheese.
