MikeMirzayanov Several of the old contests don't have solutions,and even some of the new ones like Codeforces Round 609 (Div. 2) don't have solutions.

Though the contestant is expected to implement the solution on his own after reading the editorial,but at times,when editorial isn't elaborate enough or if the contestant couldn't get the implementation part,a peek at the solution would be really helpful.

Though we can view other's submissions,but most of the code is not written for reading purpose,and the approach may be completely different from that given in editorial.

It maybe inessential for top coders,but for novices like me,it could be a boon.
