Sadly there will be no OpenCup round this weekend, but instead I invite you to participate in a mirror of t.me/umnik_team Contest which will be held on Timus Online Judge this Sunday, 12 MSK. This contest was originally held on Petrozavodsk Summer Camp 2018 (if you participated in the camp, please do not participate in this contest). This is an up-to-3-person team contest with ICPC rules (one computer per team). Difficulty level is comparable to OpenCup rounds (not Retired_MiFaFaOvO-hard, but certainly not for Div.2).
Hope you will enjoy the contest.
