How do array stacks compare to linked list stacks?

What are the main differences between array stacks and linked list stacks?

Array stacks use a contiguous block of memory, while linked list stacks use nodes that point to each other.

Which one is more efficient in terms of memory usage?

Linked list stacks can be more memory efficient for dynamic sizes, while array stacks may waste space if not fully utilized.

What about performance in terms of push and pop operations?

Both have O(1) time complexity for push and pop, but array stacks may require resizing, which can affect performance.

Are there any scenarios where one is preferred over the other?

Yes, array stacks are preferred for fixed-size data, while linked list stacks are better for dynamic data sizes.
