$1.$ What are design patterns, and why are they important in software development?

$2.$ Can you differentiate between creational, structural, and behavioral design patterns? Provide examples of each.

$3.$ How do design patterns contribute to making software more maintainable and scalable?

$4.$ Describe a real$-$world scenario where you would apply the Singleton design pattern. What problem does it solve?

$5.$ Discuss the pros and cons of using the Factory Method pattern compared to the Abstract Factory pattern.

$6.$ In what situations would you choose the Strategy pattern over the State pattern, and vice versa?

$7.$ How does the Observer pattern promote loose coupling between objects?

Provide an example.

$8.$ Explain the role of the Decorator pattern in enhancing the functionality of objects at runtime.

$9.$ Can you illustrate the Chain of Responsibility pattern with a practical example from everyday life?

$10.$ Discuss the significance of the Adapter pattern in integrating incompatible interfaces.

$11.$ Compare and contrast the Command and the Strategy patterns. When would you choose one over the other?

$12.$ How does the Prototype pattern differ from the Factory Method pattern?

Provide use cases for each.

$13.$ Describe a scenario where you might apply the Builder pattern. How does it improve the creation of complex objects?

$14.$ Discuss the role of the Proxy pattern in controlling access to objects and managing their lifecycle.

$15.$ Explain the difference between the Flyweight and the Singleton patterns.

When would you use one over the other?

$16.$ How does the Template Method pattern facilitate code reuse and extensibility?

$17.$ Discuss the concept of "anti$-$patterns" in software design. Can you provide examples of common anti$-$patterns? $18.$ Explain the principle of "favor composition over inheritance" in the context of design patterns.

$19.$ Can you identify any design patterns used in popular software applications or libraries? How do they enhance the software's architecture?

$20.$ Reflect on a personal project or experience where applying design patterns significantly improved the quality or maintainability of the codebase. What patterns did you use, and why were they effective?
