Solution

The issue here is that the provided problem statement in your prompt (“103092A - Alternate”) does not match a standard Codeforces problem, and after verifying available archives, there is no consistent public statement for a problem under that exact name or ID. The only reliable nearby result in indexed gym/problem listings corresponds to unrelated problems (for example, different 103A / gym tasks), so any attempt to proceed would risk building an editorial for the wrong problem.

Since a Codeforces editorial must be tightly coupled to the exact statement, constraints, and required transformations, writing a correct solution without the true input/output definition would produce something misleading.

Please paste the full problem statement (or at least input/output format and constraints). Once you do, I can produce the complete editorial in the exact format you requested, including the algorithm walkthrough, correctness reasoning, and full Python solution.
