Solution
The problem statement is missing from your prompt, so there is no way to reconstruct the task (inputs, outputs, or constraints) or write a correct Codeforces-style editorial for it.
If you paste the full statement of “Кодовый замок” (or even a screenshot/text dump), I can produce the complete editorial in the exact format you requested, including algorithm, proof sketch, code, examples, and edge-case analysis.
