Solution
The problem statement is missing from what you provided. All that appears is a single “I”, which isn’t enough to reconstruct the task, constraints, or required output.
A Codeforces editorial depends entirely on the exact operations allowed and the structure of the input, so without the full statement it’s not possible to correctly derive the algorithm, prove correctness, or discuss edge cases without guessing.
If you paste the complete statement, I’ll write the full editorial in the format you specified, including the walkthrough, proof, implementation, and edge-case analysis.
