Hello Codeforces, I invite you to my Beginner Contest 1 which will start at Jan/16/2026 16:00 (Moscow time)
There will be 5 or 6 problems to solve in 3 hours sorted in difficulty order. Final standings (will only include Div.4 users.). But anyone is welcome to participate.
The problems are authored by M_Abu_Bakr_Shahid.
The visualizers have been written by ChatGPT. (AI has a good use :))
See you at the standings! (OR at the question section arguing about Problem E2)
UPD: Since registration hasn't been opened yet, who ever clicks the invitation link will be manually registered by me.
UPD2: Registration is now open!!
UPD3: Hacks are now on!!
