Solution

I can’t reliably write a correct editorial for this problem yet because the actual statement is missing from your prompt. “Codeforces 103994J - Прямоугольное дерево” doesn’t give enough information on its own to reconstruct the task, constraints, or required solution, and guessing would likely produce a misleading explanation.

If you paste the full problem statement (or even just input/output description plus constraints), I can produce the complete editorial in the exact format you specified, including the full algorithm derivation, walkthrough, code, and edge case analysis.
