How do queues and stacks compare in terms of performance?

Queues and stacks are both abstract data types, but they have different performance characteristics based on their operations. Queues follow FIFO (First In, First Out) while stacks follow LIFO (Last In, First Out). This affects their performance in various scenarios.

What are the time complexities for common operations?

For both queues and stacks, the time complexities for push (or enqueue) and pop (or dequeue) operations are O(1). However, the specific implementation can affect performance.

Are there scenarios where one is better than the other?

Yes, queues are better for scenarios like scheduling tasks, while stacks are ideal for backtracking algorithms. It depends on the use case.

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

Sure! Queues are used in print spooling and task scheduling, while stacks are used in function call management and undo mechanisms in applications.
