What are some real-world examples of queue and stack data structures?

Queues and stacks are fundamental data structures used in various applications. For example, a queue is used in print spooling, where print jobs are managed in the order they are received. A stack is used in web browsers to manage the history of pages visited, allowing users to go back to the previous page.

Can you explain how a queue works in a ticketing system?

Sure! In a ticketing system, customers are placed in a queue as they arrive. The first customer to arrive is the first to be served (FIFO - First In, First Out). This ensures fairness and order in handling customer requests.

What about stacks? How are they used in programming?

Stacks are used in programming for function calls and managing local variables. When a function is called, its context is pushed onto the stack, and when it returns, the context is popped off, allowing the program to resume where it left off.

Are there any other examples of stacks in everyday life?

Yes! A common example of a stack in everyday life is a stack of plates. You can only take the top plate off (LIFO - Last In, First Out), and you can only add a new plate on top.
