Linked List vs Arrays: Which is Better?

What are the main differences between linked lists and arrays?

Arrays are fixed in size and allow random access, while linked lists are dynamic and allow efficient insertions/deletions.

When should I use a linked list instead of an array?

Use a linked list when you need frequent insertions and deletions, especially in large datasets.

Can you explain the memory usage of both data structures?

Arrays use contiguous memory, which can lead to wasted space, while linked lists use more memory due to pointers.

What are the performance implications of using one over the other?

Arrays provide O(1) access time, while linked lists offer O(n) for access but O(1) for insertions/deletions.
