On Friday, November 25 at 19:00 I'm waiting you on the Codeforces Beta Round #95 (Div. 2). This round is prepared by me. It is not easy to prepare a round, but it is always useful and interesting. By my example, I want to hint to top participants that rounds of famous people — it's always interesting!
It will be unusual round because you will find six problems. It's a little experiment — I hope that it will help each participant to find interesting problems to themselves.
I believe that the out-of-competition participants from Div.1 will have some fun solving the round.
The problem scoring is: A - 500, B - 1000, C - 1500, D - 2000, E - 2500 and F - 2500.
UPD. The competition has ended. Here are the results. First place was taken by the representative of China — liuq901. Congrats! It was nice to see such interest to the contest. Thank you for your participation!
Unfortunately, I do not have the opportunity to write a tutorial. If you deal with it I will be grateful.
