I invite you to participate in the rated Codeforces Round #499. Date and time of the round: Jul/26/2018 18:05 (Moscow time).

Those whose rating is not less than 1900 can participate in the round Div.1. Other can participate in the round Div.2.

Do not skip this contest, because the next Codeforces Round (Div.1, Div.2, or Div.3), which number begins with the digit '4', will be through the 3501 rounds!

This is the first competition I proposed. I hope that you will enjoy it.

The round will have 6 problems for each division (4 problems are common). The contest will last for 2 hours.

The main heroine of the competition is astronaut Natasha, Mars researcher. If you solve all problems, her flight will pass successfully.

Five problems of the contest are invented by me, Vladislav Zavodnik (VladProg), problems Div2.A and Div2.B are invented by Mike Mirzayanov (MikeMirzayanov), and problem Div1.F is invented by Ildar Gainullin (300iq) and Dmitry Sayutin (_kun_).

Also thanks to:
