Solution

The problem statement for “Codeforces 105490G - Разработчик задач из Сбера” is not included in your message, so there is no way to reconstruct the task, constraints, or required algorithm correctly.

An editorial at the level you’re asking for depends entirely on knowing what structures are involved, what transformations are allowed, and what is being optimized or computed. Without that, any solution would be guesswork and would very likely describe the wrong problem.

If you paste the full statement (or even just the core description and constraints), I can write the complete editorial in the exact format you specified, including the full algorithm derivation, proof sketch, code, and edge case analysis.
