Hello, Codeforces!
We, zeyd1234 and Arbuzik342, are glad to present to you the final round of our contest!
Participants will face two independent tracks: A&DS-1 and A&DS-2. The winner of each track will receive prize from the Sirius Educational Center.
Format and Structure
Anyone within the rating limits can participate in the final. * Problems D, E, F, G in the A&DS-1 track and problems A, B, C, D in the A&DS-2 track are shared. * The rest of the problems in each track are unique. * The contest duration is 4 hours.
Each problem is divided into several subtasks and is scored in points. Please note: the problems are NOT ordered by difficulty! We recommend reading all problem statements before starting to solve.
Schedule and Virtual Participation
The contest starts at 18:00 MSK on October 18, 2026.
If you cannot participate in real-time, you can start a virtual contest within 24 hours after the end of the round — your result will still count towards the final standings.
Winner Determination Rules
The final standings are based on the total points. In case of a tie in points, the priority is given as follows: 1. Participants who successfully passed the qualification round. 2. Participants with fewer wrong submissions (a submission is not considered wrong if it fails on sample tests or gets a Compilation Error).
Thank you all, and good luck in the final!
