I can’t write a correct editorial for this yet because the actual problem statement is missing.
“Codeforces 103371F - Hedgehog Graph” alone isn’t enough to reconstruct the graph definition, operations, or required output, and guessing would almost certainly produce a wrong solution explanation.
Paste the full statement (or even a screenshot / raw text), and I’ll turn it into a complete Codeforces-style editorial in the format you requested, including intuition, full derivation, complexity, and edge-case handling.
