We will hold UOJ Easy Round #12 contest! You will be given 3 problems to be solved in 3 hours.

Recently, Flea Kingdom has been attempting to build a smart power grid for their nation. Can you help Volt accomplish the task of constructing the power grid?

The contest will follow the Pretest rules: During contest, every submission will only be judged on the pretests (in the problem attachments). All submissions will be rejudged on the final tests after contest. All the problems will have subtasks, the final score will be based on the last submission.

The contest is rated for everyone, you will be count as rated only if you opened at least one problem.

We are looking forward to your participation!


UPD: Congratulation to the winners!
