How do stacks and queues perform in different scenarios?

What are the performance differences between stacks and queues?

Stacks and queues have different performance characteristics due to their data structures. Stacks use LIFO (Last In, First Out), while queues use FIFO (First In, First Out). This affects their time complexity for operations like push, pop, enqueue, and dequeue.

Can you give me examples of when to use each?

Sure! Use a stack for scenarios like undo mechanisms in applications, while queues are great for task scheduling or managing requests in a server.

How do their performance metrics compare in terms of time complexity?

Both stacks and queues generally have O(1) time complexity for push and pop (or enqueue and dequeue) operations. However, the choice between them depends on the specific use case.

Are there any real-world applications that highlight their performance?

Yes! For instance, web browsers use stacks for backtracking through pages, while print spooling systems use queues to manage print jobs.
