Hello Codeforces,↵

I'm glad to invite you to our first contest [contest:1439] and [contest:1440] which will be held at [contest_time:1439] . The problems are invented and prepared by [user:AliShahali1382,2020-11-15], [user:Mehrdad_Sohrabi,2020-11-15], and [user:Mohammad.H915,2020-11-15]. The round is rated for both divisions. You will be given **5 problems** and **2 hours 15 minutes** to solve them. I recommend you to read all the problems :)↵
