Hello everyone!↵
↵
I would like to invite all of you to participate in October Circuits '20. It's a coding marathon that opens at Oct 17, 15:30 UTC and runs for 7 days, closing on Oct 24, 15:30 UTC. Please make sure to [check your time zones](https://www.timeanddate.com/worldclock/converter.html).↵
↵
The problems were prepared by me. Thanks to [user:Arpa,2020-10-17] for coordination and [user:MhdMohammadi,2020-10-17] for testing and [user:haas,2020-10-17], [user:Haghani,2020-10-17], ... for creating [tps](https://github.com/ioi-2017/tps) and [user:MikeMirzayanov,2020-10-17] for testlib.h .↵
↵
Problem statements are short but they contain _easy to ignore_ story parts, the stories are about two character named M and Y:↵
↵
↵
↵
This coding marathon challenges you with 8 problems.↵
You are expected to solve **7 algorithmic and 1 Approximate** programing problem over a period of 7 days.↵
↵
The timeline of the challenge is as follows:↵
↵
- Day 0: Problem 1, Problem 2, Problem 3↵
↵
- Day 1: Problem 4, Problem 5↵
↵
- Day 4: Problem 6, Problem 7↵
↵
- Day 6: Problem 8↵
↵
- Day 7: Challenge ends↵
↵
↵
**New problem statements will be published every 48 hours.**↵
↵
Remember, this is a **rated contest** and there are amazing vouchers for **top three coders**.↵
↵
For more information, visit the contest's official [web page](https://www.hackerearth.com/challenges/competitive/october-circuits-20/).↵
↵
**UPD:** There is some defects in **some of tests** for problems **Two paper I** and **Expectation**, I fixed tests but because of ↵
incomprehensible hackerearth **admins** neither me or [user:Arpa,2020-10-21] are not allowed to modify tests so the only way is to consider score in problem Two paper I is from **64** and in problem Expectation is **60** (they are all correct), **Sorry** all.
