Flexibility and Reusability:?

Short answer: The strategy pattern allows algorithms to be swapped at runtime, making the code more flexible. You can add new sorting algorithms without changing the context class, thus adhering to the Open/Closed Principle (open for extension, closed for modification).

Real-world example (ShopNest)

Use a GoF pattern in ShopNest only when it removes duplication or makes a change safer—explain the problem it solves in the interview.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
