Q3. What is the difference between functional and object-oriented programming?
Ans. 
Functional programming focuses on functions and immutability, while object-oriented programming focuses on objects and encapsulation.
• Functional programming uses pure functions that do not have side effects.

• Object-oriented programming uses objects that encapsulate data and behavior.

• In functional programming, data is immutable and functions are first-class citizens.

• In object-oriented programming, objects can have state a...read more

Q2. Explain the difference between a stack and a queue . Provide an example of when you would use each?
Ans. 
A stack is a data structure that follows the Last In First Out (LIFO) principle, while a queue follows the First In First Out (FIFO) principle.
• Stack: Last In First Out (LIFO), used for function calls, undo operations.

• Queue: First In First Out (FIFO), used for printing tasks, message queues.
