Discuss the role of the Visitor pattern in Object-Oriented Programming and how it enables the separation of algorithmic operations from the object structure.

The Visitor pattern allows for the definition of new operations on a complex object structure without modifying the structure itself. It achieves this by separating the algorithmic operations (visitors) from the object structure (elements) and allowing visitors to visit and perform operations on different types of elements. This promotes extensibility and maintainability by decoupling the implementation of operations from the object hierarchy.
