Codeforces Round 1048 (Div. 1, Div. 2)

Revision en7, by wjy666, 2025-09-08 20:36:20

Hello, Codeforces!

We are glad to invite you to participate in Codeforces Round 1048 (Div. 1) and Codeforces Round 1048 (Div. 2) on 08.09.2025 17:35 (Московское время).

The round will be rated for everyone. You will be given 6 problems and 3 hours to solve them in both divisions. Some problems will be divided into subtasks.

The problems were authored and prepared by installb, wjy666, tarjen, StarSilk and 2014CAIS01.

We would like to thank:

The scoring distribution is below.

  • Div. 2: $$$ 500-1000-1500-2250-(2250+750)-3500 $$$
  • Div. 1: $$$ 500-1250-(1250+750)-2500-(2750+1500)-4250 $$$

Good luck to everyone! (=^・ω・^=)

UPD:Unfortunately, it was discovered very lately (2 hours after the contest began) that the statement was missing an important condition. The correct statement should include the line "The operation 2 can only be applied at most once." The statement will be corrected soon.

We believe this issue affected many participants of this round, and therefore we have to declare this round unrated. We sincerely apologize for this mistake.
