Hello everybody!
On Mar 3, 10:00 Moscow time, Round 1 of Yandex.Algorithm 2018 competition will take place. I wrote the majority of the problems in this contest, with some additional help from GlebsHP.
I would like to thank GlebsHP for all his help with coordinating this round, MikeMirzayanov for polygon, and of course, everyone who took the time to test this round.
See you in the competition soon!
