I would like to invite you to Kyoto University Programming Contest (KUPC), which will be held on 1 Oct. (4:00 — 9:00 GMT). Problem writers consist of several students in Kyoto University. The contest will be held on AtCoder. The contest is unofficial, so it's unrated.
The contest duration is 5 hours, and there will be 12 problems. The first a few problems are easy, so I'm sure everyone can enjoy the contest. On the other hand, a few problems from the last are probably interesting and though enough for high rated coders. We hope lots of people will compete in our contest. Good luck and have fun.
