Solution

I can’t reliably write a correct editorial for this problem yet because the statement section is empty. “Codeforces 1051943 - Лес” alone isn’t enough to reconstruct the task without risking hallucination, and that would defeat the purpose of a learning-focused editorial.

If you paste the full problem statement (or even a screenshot / text in Russian), I’ll produce the complete senior-level editorial in the format you specified, including a full derivation, algorithm, proof sketch, implementation, and tests.
