Hi all!
The 2018 ACM-ICPC Asia Shenyang Regional Contest has ended on October 21. At this site, 186 official teams and 6 guest teams selected from the preliminary online contest have competed in 5 hours, trying to solve 13 problems.
We are glad to invite you all from Codeforces, one of the greatest programming communities, to participate in its online-mirror contest, 2018-2019 ACM-ICPC, Asia Shenyang Regional Contest!
Please notice the online-mirror contest will start at an unusual time, Oct/21/2018 04:00 (Moscow time), when we are able to answer your questions during the online contest. By the way, we have added the onsite board, so when you are participating (during the mirror contest or virtual participation), you may take advantage of it!
This contest follows the ACM-ICPC rule and it will be unrated. Both personal registration and team registration are recommended. You may register for this contest 6 hours before it starts, but it is temporarily inaccessible before registration starts.
Also, many thanks to:
- Teachers, volunteers and technical staff from Northeastern University for holding such a wonderful contest;
- AHdoc, Claris, niike0goood, quailty and me for problem setting;
- yefllower, zscc, wangyenjen, adrien1018, eddy1021, waynetuinfor, boook, johnchen902, yp155136 and pr3pony for testing;
- MikeMirzayanov for Codeforces and Polygon platforms;
- icpc.foundation, JetBrains and Jisuanke for sponsoring the regional contest.
Besides, we kindly ask everybody who has already read the problems not to participate or discuss solutions in public before the contest has ended. Please keep the sportsmanship all the time!
Hope you enjoy the problems!
UPD1: Our sponsor Jisuanke will hold another online-mirror contest soon after the contest on Gym. If you missed this one, you could participate the other one, which will start on Saturday, November 25, 2018 at 12:00 (UTC+8) without the onsite board.
UPD2: Registration starts. You may view this page to register.
UPD3: Contest has ended. Any discussion will be greatly appreciated. If needed, we will discuss solutions after tomorrow.
