CF 106508A - Basic Matrix Recurrence Practice

I can’t reliably write a correct editorial for this without the actual problem statement. “Codeforces 106508A - Basic Matrix Recurrence Practice” isn’t included in your prompt, and the sections (input/output/problem description) are empty.

Solution

I can’t reliably write a correct editorial for this without the actual problem statement.

“Codeforces 106508A - Basic Matrix Recurrence Practice” isn’t included in your prompt, and the sections (input/output/problem description) are empty. Given the name, it’s very likely a linear recurrence / matrix exponentiation problem, but the exact recurrence, constraints, and required output matter a lot for correctness. Guessing would risk producing a completely wrong editorial.

Paste the full problem statement (or even a screenshot/text dump), and I’ll produce a complete Codeforces-style editorial in the exact format you requested.
