How do different data structures compare in terms of time complexity?

Can you explain the time complexity of arrays versus linked lists?

Sure! Arrays have O(1) time complexity for accessing elements, while linked lists have O(n) for access due to traversal.

What about insertion and deletion operations?

For arrays, insertion and deletion can be O(n) because elements may need to be shifted. In linked lists, these operations are O(1) if you have a pointer to the node.

How does this compare to hash tables?

Hash tables offer O(1) average time complexity for insertion, deletion, and access, making them very efficient for these operations.

Are there any scenarios where linked lists are preferred over arrays?

Yes, linked lists are preferred when you need frequent insertions and deletions, especially in large datasets where resizing arrays can be costly.
