hello, I am getting run-error on the 4th test case of the the problem Rat chases its cheese and I don’t understand why

please help me out.
thanks.
Can u tell me the purpose of using pos.
and I got one error
if(maze[i-1][j]!=‘X’ && i-1>=0 && pos!=4)
In —>if(A && B ) first condition A is checked and if is true than second statement is checked.
now consider that maze[i-1][j] not exist as for i=0 so, u have to first write i-1>=0 and then maze[i-1][j].
Correct Format:
if(i-1>=0 &&maze[i-1][j]!=‘X’ && pos!=4)
Wrong format
if(maze[i-1][j]!=‘X’ && i-1>=0 && pos!=4)
Hit like if u get it
I used the parameter pos to ignore checks like if the call to the current position in from a node above it then it is not required to check for path from the above node.
But it will not stop infinte loop.
As in test case

U will move in loop of first square.
