Refactor Like a Pro: Ditch Hardcoded Inputs for Good

Extracting input logic into separate functions enhances code testability, maintainability, and reusability, addressing issues like hard-coded inputs and hidden dependencies. This approach allows for proper validation, improved error messaging, and separation of UI from business logic. The refactoring process involves identifying input statements, creating new functions, and adding validation. This change facilitates unit testing and adherence to the single responsibility principle, resulting in more robust and maintainable code.
