The Strategy Pattern is a behavioral design pattern that allows you to define a family of algorithms, encapsulate each one, and make them interchangeable. This pattern enables the algorithm to vary independently from the clients that use it. It is particularly useful when you need to select an algorithm at runtime based on specific conditions12.
Key Components
Context: This is the class that holds a reference to a strategy object and delegates the task to it. The context provides a unified way to execute the task without knowing the details of how it’s done1.
Strategy Interface: This defines a set of methods that all concrete strategies must implement. It serves as a contract, ensuring that all strategies adhere to the same set of rules and can be used interchangeably by the context1.
Concrete Strategies: These are the various implementations of the strategy interface. Each concrete strategy provides a specific algorithm or behavior for performing the task defined by the strategy interface1.
Client: The client is responsible for selecting and configuring the appropriate strategy and providing it to the context1.

In computer programming, the strategy pattern (also known as the policy pattern) is a behavioral software design pattern that enables selecting an algorithm at runtime. Instead of implementing a single algorithm directly, code receives runtime instructions as to which in a family of algorithms to use.
