ssense and I are glad to invite you to Unofficial Div 4 Round #1. The round will not be rated for any participants since it is unofficial. Sadly, We can not post the contest on the Gym Section, so you can virtually participate in the contest by clicking this link:
You will be given five tasks and two hours to solve them.The problems were created and prepared by ssense and SlavicG for users with a rating range from 0 to 1400 but anyone is welcome to participate in the round!
We would like to thank everyone who was involved in the round preparation:
- AlexNeagu, Grumpah, Sho10 for testing the problems and providing useful feedback.
- MikeMirzayanov for Polygon and Codeforces platforms.
Even though the contest is unrated we believe it is a really good way of practice, especially for Div 4 users. We tried our best to keep the statements short and clear and we hope you will like our problems!
UPD: You can participate whenever you want, just click the link above and virtually participate.
UPD2: Tutorial will be posted September 19 by ssense.
UPD3: Editorial is out and contest is open for practice!
Congratulations to the winners:
