Template Method Pattern:

The Template Method is a behavioral design pattern that defines the program's skeleton in a base class's method but allows subclasses to override specific steps of the algorithm without changing its overall structure. The base class declares algorithmic steps, and subclasses implement these steps as needed. The Template method ensures that the algorithm's structure stays intact, while subclasses provide the actual implementation. This pattern consists of two parts: 1. Abstract Interface or Base Class: This interface contains a template method that provides the skeleton of an algorithm, broken down into a series of steps. Each step is represented by a method, which may be abstract (requiring implementation by subclasses) or concrete (providing a default implementation). 2. Concrete Subclasses: These classes provide the specific implementation for each step in the algorithm. They can override the abstract methods defined in the base class. Imagine a coffee shop preparing coffee or tea for a client; although the steps for making drinks are similar, the details can vary based on the client's specifications. Implementation in Go:
