Solution

I’m missing the actual problem statement for Codeforces 104692B2 - Roaring Years B2 in your prompt (the “Problem Statement / Input / Output” sections are empty).

I can’t reliably reconstruct the task from the title alone without risking inventing details, which would break the correctness of the editorial.

Please paste the full statement (or even just the input/output description and constraints). Once you do, I’ll produce a complete Codeforces-style editorial in the exact format you specified.
