The problem statement is missing, so there’s no way to reconstruct the actual task, constraints, or required algorithm.
“Codeforces 103428M - 810975” looks like an internal or placeholder identifier rather than a standard contest problem name, and without the input/output definition, any editorial would be guesswork.
Paste the full statement (or even a screenshot/text dump), and I’ll produce a complete editorial in the exact format you specified, including derivation, edge cases, proof sketch, code, and test coverage.
