We have a pleasure to invite you to Good Bye 2021, which will take place on Dec/29/2021 18:35 (Moscow time). You will have 2 hours to solve the problems. The round will be rated for participants of both divisions.

This round is supported by NEAR, a company founded by former competitor AlexSkidanov. NEAR is built by many prominent competitive programmers, including twice ICPC champion RussiaMustDie and GCJ and TCO winner Egor.
The participants who end up in the first 255 positions will receive prizes. The participant on the first place will receive Ⓝ128, the next two participants will receive Ⓝ64, the next four participants will receive Ⓝ32, etc.
NEAR is a modern blockchain protocol and a development platform. NEAR applications have digital assets as a first class concept, and are hosted in a way that anyone can ascertain the correctness of their execution. This allows building applications that by design provide users with ownership over their assets, data and the power of governance.
If you want to try building on top of NEAR, join Metabuild, a hackathon running until February with $1M in prizes: https://metabuild.devpost.com/
We hope you will enjoy the problem set! Good luck!
Congratulations the winners!
