Hello everyone!

Codeforces Round #201 is scheduled to take place at Friday, Sep. 20th at 19:30 MSK(23:30 CST)

Setters are: CMHJT and me.

Testers are: error202, havaliza and tourist.

Thanks to MinakoKojima for her help in rewrite the statements into codeforces style, Delinur for her help in translating the problems to Russian, and MikeMirzayanov, who has designed such a powerful platform.

Special thanks to tourist and Gerald in giving advise about the problems so we could put them in a more proper order.

500 — 1000 — 1500 — 2000 — 2500.

We are going to use standard score distribution in both divisions. The problems are not so hard, but you need more thinking rather than coding.

Good luck!

UPD1: Congratulations to the top 5 winners in each division!
