Solution
The problem statement is missing from your message (the sections for “Problem”, “Input”, and “Output” are empty), so I don’t have enough information to write a correct editorial.
For Codeforces editorials, the exact operations, constraints, and intended solution structure are essential. Without them, any explanation would be guesswork and likely incorrect.
Please paste the full problem statement (or at least the full description, constraints, and samples), and I’ll write the complete editorial in the exact format you requested.
