CodeTON Round 3 (Div. 1 + Div. 2)

Revision en10, by tibinyte, 2022-10-31 11:59:30

Hello, Codeforces! Or, as we like to say in Romania: Nu imi amintesc sa fi adresat intrebari, Codeforces!

I am glad to finally invite you to participate in [ Add link ], which will start on [ Add link ]. You will be given 8 problems and [TBD] hours to solve them. It is greatly recommended to read all the problems, statements are short and straight to the point.

I would like to thank:

Artyom123 for gorgeous coordinating the round.
AquaMoon, mejiamejia, ugly2333, Ecrade_ for huge help in preparation and authoring one of the tasks.
[...] for testing the round and providing invaluable feedback.
freak93 for morning refreshment.
