When should I use stacks instead of queues?

When should I use stacks instead of queues?

Stacks are best for scenarios where you need to access the last item added first, like in undo mechanisms.

Can you give me an example of a real-world application for stacks?

Sure! A common example is the backtracking algorithm used in web browsers to navigate through pages.

What about queues? When are they more appropriate?

Queues are ideal for scenarios where you need to process items in the order they were added, like in print job management.

Are there any performance differences between stacks and queues?

Generally, both have similar performance characteristics, but the choice depends on the specific use case.
