Hash set and hash map are data structures used to store key-value pairs for efficient retrieval.

• Hash set stores unique values without any specific order.

• Hash map stores key-value pairs and allows fast retrieval of values based on keys.

• In Java, HashSet and HashMap are implementations of these data structures.

Compile time polymorphism is achieved through function overloading and templates.

• Function overloading allows multiple functions with the same name but different parameters.

• Templates allow generic programming by defining functions or classes that can work with different data types.

• Examples of function overloading include cout<< for different data types and sqrt() for float and double.

• Examples of templates include vector
