It seems the problem description is in an image which I can't view directly. Could you please provide the problem statement in text form (including details like the problem's requirements, input constraints, and examples)? This way I can understand the problem clearly and help you solve it.

For example, if it's a string-related problem, please mention what operations are allowed (replace, delete, insert), what the goal is (e.g., make no two adjacent characters same, find longest substring without repeats, etc.), and any input/output examples you have.

Looking forward to your text description!
