Hi CodeForces!

As we can see, during the last contest:Manthan, Codefest 19 (open for everyone, rated, Div. 1 + Div. 2), a number of codes that passed system test in problem F is wrong. And, unfortunately, there are almost no hacks during the contest. So the tests were definitely pretty weak.

I think one of the main reasons is that in each room, the number of people who passed pretest in this problem is very small (probably none), and so do the problem E and G. In this case, there are almost no chances to hack these problems.

So I suggest each participant be divided into two rooms, the first one is divided randomly, and the second one is divided by their rating. In this way we will have more chances to hack difficult problems.
