Hello, my dear lovers of algorithms and data structures.
Codeforces Round 380 will start on November 20 (Sunday), 09:05 (UTC). It will be based on Technocup 2017 Elimination Round 2. So, if you are a Russian-speaking high-school student, please take part in the Technocup 2017.
I hope you will like problems. It will be 6 problems in each division.
Good luck and bugless code
