Hi everyone! I would like to share a contest from problems I suggested in some programming school. These problems are by my own and some by Mosyagin. Is starts on this Wednesday at 18:00 Moscow time (see your timezone https://www.timeanddate.com/worldclock/fixedtime.html?day=24&month=2&year=2021&hour=18&min=0&sec=0&p1=166). You will be given 8-9 problems. I think they are educational a bit(but may be not all). I would be glad if you will participate and give me some feedback. Don't be too strict anyway it's one of my first such experience though I always wanted to make a contest. You can find contest in gym with name Kaliningrad Krosh Contest 1. It's duration 3 hours, statements will be on Russian and English.
