Hello there!! In today's contest there is one question and I submitted my solution but it is not working correctly and I am not able to figure out why it is not working. I am not able to see the test case in jury verdict also because of the seen limit on the cases. So please can anyone help me to figure out why this is not working as I already spent more than 3 hrs on this. Thank You
