CF 105176I - 命令行
The problem statement is effectively missing here. All we have is the title “命令行” and empty input/output sections, which is not enough to reconstruct the task.

Solution
The problem statement is effectively missing here. All we have is the title “命令行” and empty input/output sections, which is not enough to reconstruct the task.
A Codeforces editorial depends entirely on the actual mechanics of the problem: what operations are allowed, what the input describes, and what must be computed. Without that, any “solution” would be guesswork rather than a correct derivation.
If you paste the full statement (or even a screenshot or raw text), I can produce the complete editorial in the exact style you requested, including the algorithm derivation, correctness argument, implementation, and edge-case analysis.
