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

Queues and stacks are fundamental data structures used in various applications. For example, queues are used in print job management, where documents are printed in the order they are received. Stacks are used in web browsers to manage the history of pages visited, allowing users to go back to the previous page.

Can you give more examples of where queues are used?

Sure! Queues are commonly used in customer service systems, like call centers, where calls are handled in the order they are received. They're also used in task scheduling for operating systems, where processes are managed in a first-come, first-served manner.

What about stacks? Where else are they applied?

Stacks are used in programming for function calls, where the last function called is the first to return. They're also used in undo mechanisms in software applications, allowing users to revert to previous states.

How do queues and stacks differ in their operations?

Queues operate on a first-in, first-out (FIFO) basis, meaning the first element added is the first to be removed. Stacks operate on a last-in, first-out (LIFO) basis, where the last element added is the first to be removed.
