Hello, Codeforces community!↵

I'm glad to invite you to Codeforces Round #691 (Div. 1) and Codeforces Round #691 (Div. 2), which will be held on [contest_time:1459]. **The round will be rated for both divisions.**↵

The problems were taken (mostly) from the ByteDance — Moscow Workshops Online Contest, which is happening at the same time. They were prepared by me, [user:AndreySergunin,2020-12-17], and [user:amethyst0,2020-12-17]. We are very thankful to the testers (the usual list will appear later).↵
