It seems the problem content is in an image which I can't view directly. Could you please describe the problem in text form (like the question, given conditions, required output, etc.)? That way I can help you solve it step by step.

For example, if it's a math problem, please write down the equation or the problem statement; if it's a programming problem, share the problem description, input/output requirements, etc. Looking forward to your detailed text description!
