Hello, and, again, you are invited to a monthly contest: HackerEarth October Clash.
The contest takes place this weekend (starting time) and runs for 24 hours. 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.
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. It gets harder when trying to take part in all contests which take place tomorrow...
UPD: The contest has finished, congratulations to the colourful top 5:
The editorials were delayed (because I overslept),
almost all of them are up now.
