Strategy Pattern:

The strategy design pattern is a behavioral design pattern that enables selecting an algorithm at runtime. Instead of implementing a single algorithm directly, the code receives run-time instructions as to which of a family of algorithms to run. A strategy lets you define a family of algorithms, encapsulate each one, and make them interchangeable. This pattern allows algorithms to vary independently from the clients that use them. Imagine you're going on a trip, but the mode of transportation depends on various factors like distance, cost, and time. These factors can be considered in context. Your available transportation methods (car, bike, train, etc.) are your strategies. Based on the context (distance, cost, and time), you choose a strategy that best fits the context.
