Explain the Template Method design pattern.

The Template Method design pattern is a behavioral design pattern that defines the skeleton of an algorithm in a superclass, allowing subclasses to provide specific implementations for certain steps of the algorithm. It promotes code reuse and provides a way to define a common structure for a group of related algorithms.

In this pattern, the superclass contains a template method that defines the overall algorithm and calls several abstract methods, which are implemented by the subclasses. The template method provides a high-level view of the algorithm, while the subclasses provide the specific implementations for the individual steps.

By using the Template Method pattern, the overall algorithm can be defined in a single place, making it easier to maintain and modify. It also allows for variations in the algorithm by simply extending the superclass and implementing the necessary methods.

This pattern is commonly used in scenarios where multiple algorithms share a common structure but have different implementations for certain steps. It helps to avoid code duplication and provides a flexible way to customize the behavior of the algorithm.
