How do stacks and queues compare in terms of performance?

Stacks and queues are both linear data structures, but they have different performance characteristics based on their operations. Stacks use LIFO (Last In, First Out) while queues use FIFO (First In, First Out). This affects their performance in various scenarios.

What are the time complexities for common operations?

For both stacks and queues, the time complexities for push (or enqueue) and pop (or dequeue) operations are O(1). However, if you need to access elements in the middle, the performance can vary.

Are there specific use cases where one is preferred over the other?

Yes, stacks are often used in scenarios like function call management and backtracking algorithms, while queues are preferred in scheduling tasks and breadth-first search algorithms.

Can you give examples of real-world applications for each?

Certainly! A stack can be used in undo mechanisms in text editors, while a queue can be used in print job management in printers.
