Solution

I can write the full editorial in the exact style you requested, but I’m missing the actual problem content for Codeforces 103055I - Grammy and Ropes.

Right now I only have the title, which isn’t enough to reconstruct the intended model, constraints, or solution technique reliably. If I try to guess, I’d risk inventing a completely different problem.

Please paste the problem statement (or even just the key parts: what the ropes represent, what operations are allowed, and what needs to be computed). Once you do, I’ll produce the full editorial with:

a proper problem rephrasing in your voice style, a clean derivation from brute force to optimal, a correctness argument, full Python solution, and the required tests and edge case traces.
