Hello, Codeforces!
“Experimental Educational Round: VolBIT Formulas Blitz” will take place on February 18, 2016 at 18:00 MSK. This time the problemset is recommended for Div.2 participants.
The round will be unrated for all users and it will be held according to the standard ACM-ICPC rules. You will have 180 minutes (three hours) to solve 18 problems. There will be no open hacks phase after the round.
Our main target audience is beginners and Div. 2 members. All offered problems can be solved without conditional constructs and without loops. Only formulas are required. Assignments and functions can be used to reduce code duplication.
The topics of the problems are:
- combinatorics
- geometry
- game theory
- sequences
- other
The round is created as a part of Vologda BIT event, also as part of this event “Contest programming from zero in Java” webinars were held devoted to the topics listed above. Recordings of the webinars are available on YouTube (in Russian).
The round was prepared by me, Fyodor Menshikov mfv, Igor Andrianov igand and Oleg Strekalovsky OSt. Special thanks to Maria Belova Delinur for bugfixing the English statements and of course to MikeMirzayanov for Codeforces platform and Polygon. Polygon made our checkers and tests for this contest better.
UPD: The editorial is complete.
