Hello, and, again, you are invited to a monthly contest: HackerEarth October Clash.
The problemsetter this time is RomaWhite; I'm the tester and editorialist. After all, I have to give I_love_Tanya_Romanova a chance to compete! :D
The contest takes place this weekend (starting time) and runs for 24 hours. As usual, there should be 6 algorithmic problems with partial scoring (points are given independently for passing each test file) and 1 challenge problem. I think the problems are easier than last month, when two subtasks of one problem went unsolved by anyone.
Good luck!
Btw, round 1 of COCI overlaps with this Clash for 3 hours. That, of course, doesn't mean it's not possible to participate in both at the same time — from my own experience.
