What are the memory usage differences between arrays and linked lists?

What are the memory usage differences between arrays and linked lists?

Arrays use contiguous memory allocation, while linked lists use nodes that can be scattered in memory.

Which one is more memory efficient?

It depends on the use case. Arrays have less overhead, but linked lists can be more efficient for dynamic sizes.

Can you explain the overhead in linked lists?

Each node in a linked list requires extra memory for pointers, which can add up compared to arrays.

Are there scenarios where linked lists are better?

Yes, linked lists are better for frequent insertions and deletions, as they don't require shifting elements.
