It seems the problem statement is missing (the content appears as image placeholders which I can't view). Could you please provide the problem description in text form? This will allow me to understand the problem and help you find the solution.

If you can describe the problem (e.g., combinatorial question, grid problem, number theory, etc.) with details like constraints, required output, etc., I'll be able to assist you effectively.

Looking forward to your text description!
