Also we shall like to share with our fellow participants that there was an issue with the Servers problem this month. Our contestant Rajiv Kumar Aggarwal pointed this out soon after the contest. The test data was found to be not comprehensive and did allow a few incorrect submissions. For details please refer our comment on the wiki page. It was a glitch from our side and we sincerely apologize for the same to all our participants. We intend to work towards it and will try and ensure that it does not repeat
