Solution

I cannot produce a correct editorial yet because the problem statement is not actually available in the prompt or in a reliable extracted form. What I currently have is only the contest identifier, and Codeforces problem IDs like this are not enough to reconstruct the task uniquely.

If I try to proceed anyway, I would risk inventing rules, which would make the entire editorial meaningless.

Please paste the full statement of 103608D - Необычная ловушка, or at least the Input/Output description and constraints. Once you do, I’ll write the complete Codeforces-style editorial exactly in the format you specified, including the full algorithm derivation, proof sketch, code, and edge-case analysis.
