Hello, Codeforces!

I am glad to invite you to the round for beginner coders. There will be 6-7 problems. Try to solve all problems. The contest will be in IOI style. Thanks for testers of the round and for the good feedback.

I tried to choose and do good tasks. I hope you find them interesting. Read the conditions from all tasks. It is not guaranteed that the tasks are in order of increasing difficulty.

Would you like to participate in this contest? Follow the link. Participate in virtual participation and solve problems.

Sorry for the bad translation, LaTeX formatting or for not clear statements. I tried my best and this my first contest. If you like this round, then in the future I will try to make more such contests.

Good luck in CP :D

UPD1: Editroial here

There is some problem in test cases of B. The given n and length of string differ , leading to RTE verdict.
