On what basis questions are put into categories of beginner, easy, medium hard? I see problems with very few(even 0 submissions) in easy section. Shouldn’t they be sent in hard section???
Some of this is probably a bug in Codechef. For example, at the time of writing, this problem is listed in the Easy list as having 0 successful submissions, but if you look at the Submissions list for it, you see plenty of 100pt solutions.
Also, newly-added Problems will have fewer submissions.
i think you should solve the problems with maximum submissions first.
