Solution
The problem statement you provided is essentially empty, so there is no defined input format, output requirement, or constraints to base an editorial on.
For a Codeforces editorial, the entire solution depends on details like what structure “榕树之心” refers to, what transformations or queries are involved, and what needs to be computed. With only the title, any attempt to write an algorithm would be pure guesswork and would not meet the correctness standard you’re aiming for.
If you paste the full problem statement (or even just the input/output description and constraints), I can produce a complete, structured editorial in the exact format you requested, including intuition, optimal approach, proof sketch, code, and edge case analysis.
