The problem statement is effectively missing here. What you provided only contains the title, with no input/output description, constraints, or sample behavior to anchor a solution.

Solution
The problem statement is effectively missing here. What you provided only contains the title, with no input/output description, constraints, or sample behavior to anchor a solution.
A Codeforces editorial depends entirely on the underlying task structure, since the choice of algorithm, the correctness argument, and even the complexity target are all determined by the constraints and what is being computed. Without that, any “solution” would be invented rather than derived, which would defeat the purpose of a reliable editorial.
If you paste the full statement (or even just the input format, output format, and a sample), I can write the complete step-by-step editorial in the exact style you requested, including the derivation, implementation, and proof.
