Solution
The problem statement for “Codeforces 106318D - Seating Arrangement” is missing from your prompt, so I don’t have the actual rules, input format, or what needs to be computed.
An editorial depends entirely on those details, especially for identifying the core invariant and optimal approach. Without them, anything I write would be guesswork and would not meet the standard of a correct Codeforces solution walkthrough.
Paste the full problem statement (or even just the key parts: description, constraints, and samples), and I’ll write the complete editorial in the exact format you specified.
