I was doing this problem in November circuits, due to big data constraints
i used unsigned long long int datatype which led to wrong answer in all my test cases. After a lot of debugging when i changed the datatype to long long int, then my code passed all the test cases. What is so wrong with unsigned long long int??

Welcome to codereview. The question "why does it work?" or "why doesn't it work?" is off-topic for codereview, and would be better suited for stackoverflow.com . If you want a review of the working version of your code, please note that the code must be included in the post itself, rather than behind a link: codereview.meta.stackexchange.com/a/1309/22697
