An editorial depends entirely on the underlying model of the problem, what the input encodes, what operations are allowed, and what must be optimized or computed. Without that, any solution I write would be a guess, and for Codeforces-style problems the structure matters too much for guessing to be meaningful.
If you paste the full statement (or even just input/output description and constraints), I can produce the complete editorial in the exact format you specified, including the derivation, algorithm walkthrough, and implementation.
