Editorial

I just registered for : Codeforces Round #574 (Div. 2) Interestingly it shows me as a participant out of contest. I comprehend that as one who won't be rated in the contest . I checked the registrants page other purple folks also have an asterisk symbol with their names (out of contest).

So is div 2 not going to be rated for >= 1900 people ?

I am trying to submit solution for a question of last year ICPC India online round on codechef. Question : A tale of two trees Link : Your text to link here... But it doesn't allow to submit questions in C++. Can anyone help how to test my solution for the question?

Thanks.
