Good Evening Codeforces! ^_^
This round is unrated; please read this to know why.
I invite you to participate in Codeforces Round #682 (Div.2) taking place on Nov/13/2020 17:35 (Moscow time). The round, authored by Anti-Light and me, is rated for users rated less than 2100, while other users can participate non-competitively.
The round features six problems, and you have 2 hours to solve them. There may, or may not, be an interactive problem; regardless, you should know how to deal with them.
I would, now, like to thank–
- antontrygubO_o for coordination.
- AwakeAnay and AsleepAdhyyan for helping me solve one of the problems.
- BRCode for making 3b1b-style video editorials of the problems!
- knightron00 for helping with preparation.
