Fresher / Software Engineer Answer

The Strategy Design Pattern is a programming concept that helps us make our code more flexible. It lets you define different ways to do something and choose which one to use at runtime. It’s like having different tools in a toolbox and picking the right one for the job when we need it.

The Strategy Design Pattern is a well-known behavioural design pattern used in industry. It provides a structured way to define a set of interchangeable algorithms, encapsulate them within separate classes, and then dynamically choose the appropriate algorithm to execute based on specific requirements.

This pattern enhances code flexibility and promotes separation of concerns, making it easier to maintain and extend software systems.
