Solution

The problem statement for Codeforces 105501F - Burt (Hard Version) is missing from your prompt, so there is no way to reliably reconstruct the solution, constraints, or even the task definition.

For a Codeforces editorial, the structure and algorithm depend entirely on details like what operations are allowed, what needs to be optimized, and how the input is formed. Without that, anything written would be guesswork and very likely incorrect.

If you paste the full statement (or even just the core description and constraints), I can produce the complete editorial in the exact format you requested, including the algorithm walkthrough, proofs, and implementation.
