Hi @ashu.heretocode your solution to the problem is absolutely correct. The only reason you are getting the wrong answer verdict is because your are printing YES instead of yes and NO instead of No.

I would suggest you to always read the problem statement and the input/output formats very carefully.
Hope this helps :slight_smile:
