Recently one of my friends shared this problem with me. I really found this beautiful and thought of giving it a share.I won't spoil the essence of this problem, but definitely expecting some nice approaches and solutions in the comment.

Recently I can across this problem in one of the coding tests, and am really clueless of how to solve it. Help please.

Is there any technical issue in the Codeforces site. As from the past couple of days when I am opening my "Submissions" page its only showing a few of my all submissions.

Kindly reply if you guys are also facing the same issue of not being able to see all your submissions
