Hello folks, Need some help in debugging.. The question is on the right : Ques This is the code I submitted : Code I don't know why I'm getting signed integer overflow, inspite of having all the variables as long long. Can someone enlighten me on what I'm missing. [contest:918][problem:1915C]

Instead of having a common discussion page in the editorial section of the contest. We could have a mini discussion page for each problem.. This would reduce the burden of searching for the problem you need. Any thoughts on this?

Btw this is my first blog on Codeforces. Currently a newbie. Looking to break into cyan pretty soon!
