I don’t have the actual problem statement for Codeforces 106020I - MST Queries, so I can’t reliably reconstruct the task, constraints, or required technique without risking inventing details.
If you paste the statement (or even just the key parts: input format, what each query asks, constraints), I’ll write the full editorial in the exact style you specified, including the algorithm derivation, correctness argument, and implementation.
Send it over and I’ll continue from there.
