On April 4th, V (XVI) Volga Region Open Team Student Programming Contest was held in Samara State University. And now, we invite everyone who haven't already participated in the championship to join the Codeforces training contest version on June 21st (11:00 — 16:00 MSK, UTC+3). We believe that participants of any level will find problems that will be interesting for them. The contest will probably be mostly interesting to participants with violet and orange levels (difficulty is 4 stars).

This contest uses ACM ICPC rules.

Please, do not use the Internet, prewritten code and other sources: participants of the championship could not use any of these.

Contest was prepared by Dmitry Matov (Nerevar), Constantine Drozdov (I_love_natalia), Andrew Antipov (Sinner), Andrey Gaidel (Shlakoblock), Elena Rogacheva (elena), Sergei Shteiner (steiner), Alexander Efimov; Igor Baryshnikov (master_j) was of great help in English translation.
