What are the differences in complexity between arrays and linked lists?

Arrays have a fixed size and allow O(1) access time, while linked lists have O(n) access time but can grow dynamically.

Can you explain why linked lists have O(n) access time?

Sure! In a linked list, you must traverse from the head to the desired node, which takes O(n) time.

What about insertion and deletion operations?

Insertion and deletion in linked lists are O(1) if you have a pointer to the node, while in arrays, they can be O(n) due to shifting.

Which data structure is better for large datasets?

It depends on the use case. If you need fast access, arrays are better; for frequent insertions/deletions, linked lists are preferable.
