Category	Design Pattern	Short Description
Creational	Singleton	Ensures only one instance of a class exists.
	Factory Method	Creates objects without exposing creation logic.
	Abstract Factory	Creates related families of objects.
	Builder	Builds complex objects step by step.
	Prototype	Creates new objects by cloning existing ones.
Structural	Adapter	Converts one interface to another.
	Bridge	Separates abstraction from implementation.
	Composite	Treats individual and grouped objects uniformly.
	Decorator	Adds functionality dynamically.
	Facade	Simplifies access to a complex subsystem.
	Flyweight	Shares objects to reduce memory usage.
	Proxy	Controls access to another object.
Behavioral	Chain of Responsibility	Passes a request through multiple handlers.
	Command	Encapsulates a request as an object.
	Interpreter	Interprets a defined grammar or language.
	Iterator	Sequentially traverses a collection.
	Mediator	Centralizes communication between objects.
	Memento	Saves and restores an object's state.
	Observer	Notifies dependent objects of state changes.
	State	Changes behavior based on internal state.
	Strategy	Selects an algorithm at runtime.
	Template Method	Defines an algorithm skeleton while allowing subclasses to customize steps.
	Visitor	Adds operations to objects without modifying their classes.
