Test case failed 3

#1


why 3 test case are failing?

#2

Before accessing ar[x][y], you should check if x and y are valid.
In your code, make sure you are always having this condition.

Didnt get it . Like arr[][] is the input array?

Apologies for a delayed response.
I meant to say that if you have your array ar[5][5] and you are trying to access ar[7][4], it wont happen.
So always have a condition that if i<bound and j<bound, then only access ar[i][j].
In your code, this condition is required.
