Solution

The problem statement is missing, so I don’t have the actual definition of what “Binary Tree” (CF 105484G) is asking for.

Right now I only see the title and metadata, but no description of:

the input format, what operations or tree properties are involved, or what needs to be computed. Without that, it’s not possible to derive a correct algorithm, and anything I write would be guesswork rather than a real editorial.

If you paste the full statement (or even just the core description and constraints), I can produce a complete Codeforces-style editorial in the format you specified, including the brute force reasoning, optimized approach, walkthrough, and tested Python solution.
