Help me identify the mistake in the code.

When a path does not exist, you have to display “NO PATH FOUND”. It is mentioned in the question. The rat can move in all 4 directions, so it is possible that it might visit a cell again and get stuck in recursion. So before making recursive calls, we have to check if the cell is already visited or not.
I made the required changes to your code: https://ide.codingblocks.com/s/576597
