2017 CMUT BeihangU Contest, Editorial

Правка en7, от skywalkert, 2020-04-22 22:16:43

This editorial corresponds to 2017 Chinese Multi-University Training, BeihangU Contest (stage 1), which was held on Jun 25th, 2017.

There are 12 problems in total. You can solve them as a team member or an individual in a 5-hour contest. By the time you join as virtual participants, 770 teams, or even more, will compete with you virtually.


Editorial in the English version has been completed, which is a bit different from its Chinese version (mostly because I don't want bad editorials to ruin the contest, lol). However, for the sake of hiding spoilers, editorials are locked and will be shown as the following conditions are met:

  • Editorials for the easiest 4 problems will be revealed after the replay (all unlocked);
  • Each for the hardest 5 will be released if the corresponding problem has been solved by at least 5 users or teams on Codeforces::Gym (4 unlocked);
  • Each for the others will be published when the relevant problem has been solved by at least 10 users or teams in virtual participation (including the replay) on Codeforces::Gym (all unlocked).

Or you can find solutions in comments?
