Solution

I can write the editorial, but the problem statement content in your prompt is empty, so I do not have the full specification needed to produce a correct explanation, proof, algorithm, code, examples, and tests.

Please paste the complete statement for Codeforces 102870J (including the exact input/output format and constraints), and I’ll generate the full editorial in the requested structure and style.
