Revision en5, by Syloviaely, 2018-12-18 08:38:27

Hello, Codeforces!

The 2018 ICPC Asia-East Continent Final has ended on last Sunday. At this site, over 380 teams have competed in 5 hours, trying to solve 12 problems.

The problems are prepared by CommonAnts, Claris and me. Thanks to skywalkert, quailty, zscc, yefllower,niike0goood, AHdoc, C_SUNSHINE for discussing and testing the problems, whzzt, sunset, TLE for their amazing performance in the test contest.

Moreover, special thanks to CommonAnts, skywalkert, C_SUNSHINE,Claris for preparing the statement. To ensure the correctness of the statement, they corrected it for over 180 times before the conetst.

Although I had set 6 ICPC contests before, I felt a lot of difference between official contests and online contests. In response to the responsibility, we tried our best to seek out the most interesting tasks and make a tradeoff between difficulty and discrimination.

I'm proud of this contest, and I could hardly wait for sharing these interesting ideas to you. We will hold two online-mirror contests, just choose the one which is convenient for you:

  1. One is this week's OpenCup. The contest will start on Sunday, December 23, 2018 at 16:00 (UTC+8) .
  2. The other will be held on Codeforces. In our plan, the contest will start on Saturday, December 29, 2018 at 18:00 (UTC+8). The contest follows the ACM-ICPC rule and it will be unrated.

Besides, we kindly ask everybody who has already read the problems not to participate or discuss solutions in public before the OpenCup contest has ended. Your cooperation will be greatly appreciated.

Hope you enjoy the problems!
