We are thrilled to invite you to participate in the Replay of National High School Programming Contest 2021, tomorrow, June $$$14$$$, at 07:30 pm BST. To participate all you have to do is to create an account on Toph. You can register here.

You will be given $$$12$$$ problems and $$$5$$$ hours to solve them. The contest will follow standard ICPC rules.
We tried to create very engaging problems, compact statements, and robust datasets for this round. Hopefully, the participants, with a rating of less than $$$2600$$$, will find the problems stimulating and interesting.
Also, there will be an editorial shortly after the round ends.
UPD: The problems are available for practice here. Editorials are attached to each of the problems separately.
