Hello everyone!

CF round #333 (both divisions) is going to take place soon. The authors of this round are me and Baklazan.

By total coincidence, I'm the author of even-indexed problems and Baklazan the author of odd-indexed problems. Now I'm going to let you wonder if it's 0-based or 1-based :D.

As usual, thanks to GlebsHP for his help (in particular, helping us not overkill the problems), MikeMirzayanov for CF and Polygon.

I wish good results and rating changes to those who earn it, as well as a zero-sum rating update to everyone.

According to tradition, the score distribution will be revealed right before the contest.
