# Not able to pass one test case in MARLA

I am not able to pass one test case from the Second subtask in MARLA. I am getting runtime error. Link to my solution: https://www.codechef.com/viewsolution/33231172

Have you tried a case with a 1000x1000 grid with only ones? That would probably exhaust the default recursion limit for python.

Thank you so much. My answer got accepted after increasing the recursion limit.
