Solution
The problem statement is missing from your prompt, so there’s no way to correctly derive the solution, constraints, or algorithmic structure for “Codeforces 102993I - Valuable Forests”.
For a Codeforces editorial, the structure and method depend entirely on details like what the forest represents (graph, tree, weighted nodes, queries, etc.), what is being optimized or counted, and the constraints. Without that, any attempt to write a solution would be guesswork and would almost certainly be wrong.
If you paste the full statement (or even a screenshot/text dump), I’ll produce the complete editorial in the exact format you specified, including the algorithm walkthrough, complexity analysis, code, and test cases.
