Hello, Codeforces!
The 2020 ICPC Asia Macau Regional Contest has ended on May 29th.
The problems for this contest were prepared by Zhejiang University. We are glad to announce that we have published the contest, The 2020 ICPC Asia Macau Regional Contest in Codeforces::Gym for you to practice. Feel free to start virtual participation or to solve the problems individually. For virtual participation, the contest is 5 hours in length and follows usual ICPC rules. Team participation is recommended, but it is also possible to participate individually. The ghosts of the onsite participants are available, you may take advantage of it.
