Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

“Codeforces 104009K - Restricted Tree” is just a title here, but the key details are exactly what determine the solution: what “restricted” means, what operations or queries exist, and what needs to be computed on the tree. Without that, any attempt would turn into guessing, and it would almost certainly be wrong.

Paste the full statement (or even a screenshot / rough description), and I’ll turn it into a complete Codeforces-style editorial in the format you specified, including the algorithm walkthrough, proof idea, implementation details, and edge cases.
