Hi!
This round is sponsored by esports team cybercats. The team was founded in October 2021, by me and subscriber.
We currently have a Dota 2 roster, playing in the second division of EEU DPC. Come support us on streams and in the comments!
As a thank you to Codeforces and the competitive programming community, we decided to make this round and give away 100 plush cybercats!
The prizes will be awarded to the first 100 places in the round.
