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.
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.
UPD: There are some defects in some of tests for problems Two paper I and Expectation, I fixed tests but because of incomprehensible hackerearth admins neither me nor Arpa 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 from 60 (they are all correct), Sorry all.
UPD2: Editorial is published, it should be published by HacherEarth weeks ago.
