My code was failing for the fourth test case. Could anybody know what was the test case or where my code was failing to meet the test cases conditions?

for this test case your code gives no , but it should be yes .

and the fourth case you are talking about is actually a test file , noone will be able to tell you about that because codechef keeps test file secret .
