Solution
I don’t have the actual statement for Codeforces 103182F - Secure documents in your prompt, so I can’t reliably derive the algorithm, constraints, or examples needed to write a correct editorial.
For a problem-specific editorial at Codeforces level, the exact rules of the system (what “secure documents” means, operations allowed, constraints, input format, etc.) completely determine the solution approach. Without that, any “full solution” would be guesswork and very likely wrong.
Paste the full problem statement (or even just the key parts: input format, what needs to be computed, constraints, and samples), and I’ll write the complete editorial in the exact style you requested.
