I can’t write a correct editorial for this yet because the actual problem content is missing. Right now the statement only shows the title, input/output sections are empty, and there’s no description of what operations, structures, or constraints are involved.

Solution

I can’t write a correct editorial for this yet because the actual problem content is missing.

Right now the statement only shows the title, input/output sections are empty, and there’s no description of what operations, structures, or constraints are involved. For a Codeforces editorial, that information is the entire substance of the solution; without it, any “solution” would just be guessing.

If you paste the full problem statement (even a screenshot or raw text), I can immediately produce a complete, structured editorial in the exact format you requested, including the algorithm derivation, correctness argument, code, and edge-case analysis.
