Hello Codeforces,

I was solving this problem on hackerrank.

I successfully solved it by submitting this (for hackkerank site). All test cases passed.

But this submission(for hackkerank site) fails on this test case. Why??

Also when i try to implement the above solutions on my computer they run indefinitely on other test cases(which got accepted on hackerrank) for large values of n and m.

Help!!
