Codeforces Beta Round #28 (Codeforces format)
By Polichka, 14 years ago, translation, In English

Attention-Attention!!!

Today Saratov SU #1 (Gerald, Polichka, Fefer) team invites all of you to take part in Codeforces Beta Round #28. 

We began studing sport-programming in school. But when we entered the Saratov State University we took it seriously and made our way from SU #7 to Saratov SU #1. Now our first-grade ambition is to justify this number.

We are going to offer you 5 interesting problems. You will be helping some good people to deal with their problems, will be solving some administrative tasks, will be playing some interesting games and also will be saving the World.

Thanks to everyone for their help in preparing this round. 

Successful hacks and fast accepteds!
With best regards, Saratov SU #1.

I felt the questions were relatively tougher than previous sets, but they are nice problems. Also, I found description of problems little lengthy and not able to understand it in first go. Had to read 3 - 4 times. Anyway, thanks a lot for all your work and hope to see many more coming :)

      Saratov SU #1 in this picture is a very good advertisement of your university (I wish I studied there :P) so you should stay nr 1 for a long time.

I don't understand problem A. Could some one explain it please?

Also, is there an analysis for every round?
as I can't find the analysis for most of rounds (#25, 26, 27 to name just a few).

Thanks very much.

      Fefer, May I ask you a question about Hack?
      The STANDING said : "double click ", I had tried, but only can see his submissions history. Doest it is the same as Topcode's Challenge? But I can't see his code, how can I hack?
      waiting for your reply... thx.

        You can hack only the solutions submitted in your room. Before you can see the solutions and hack some, you have to lock the problem which you intend to hack - in the Problems tab you'll see a 'lock' button.
