Make sure to restructure the existing code without changing its external behavior to improve readability, maintainability, and performance.\n           2. Refactor the code to make code easier to understand by breaking down complex logic into simpler, more readable components. \n           3. Make sure that the refactored code addresses the code duplication and code smell issues.\n           4. Refactored code should include inline documentation and code comments to reflect the changes made to the code\n           5.
