How does a stack compare to a queue?

Can you explain the difference between a stack and a queue?

Sure! 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.

Can you give me an example of how each one works?

Of course! In a stack, you can think of it like a stack of plates; you add and remove plates from the top. In a queue, it's like a line at a ticket counter; the first person in line is the first to be served.

What are some real-world applications for stacks and queues?

Stacks are used in function calls and undo mechanisms in software, while queues are used in scheduling tasks and managing requests in servers.

Which one is more efficient for certain tasks?

It depends on the task! Stacks are more efficient for tasks that require backtracking, while queues are better for tasks that require order preservation.
