Solution

The editorial request cannot be completed as written because the actual problem statement for Codeforces 105515C - “Эффективные ветрогенераторы” is missing from the prompt. Without the statement, any attempt to reconstruct the task would be speculative, and that would break the requirement that the solution be concrete and faithful to the original problem.

To produce a correct Codeforces-style editorial, I need at least one of the following:

The full problem statement, or

A link or excerpt containing input/output description and constraints, or

A brief description of what the problem asks (even informal is fine).

Once you provide that, I will write the full editorial in the exact format you specified, including algorithm walkthrough, proof sketch, code, and test cases.
