Solution

I’m missing the actual statement of Codeforces 106215G - Graph and Information Delivery, so I can’t accurately reconstruct the problem, constraints, or the intended solution.

Right now I only see the template, not what the graph looks like, what “information delivery” means in this context, or what queries/outputs are required. Without that, any editorial would be guesswork and very likely wrong.

Paste the full problem statement (or even just the key parts: input format, operations, and goal), and I’ll write the complete editorial in the exact style you requested.
