What data structure is best for frequent insertion and deletion?

For frequent insertion and deletion, a linked list is often preferred due to its dynamic size and efficient operations.

Can you explain why a linked list is better than an array for this?

Sure! In a linked list, you can insert or delete nodes without shifting elements, which is required in an array.

Are there any other data structures that are good for this purpose?

Yes, other options include balanced trees like AVL trees or Red-Black trees, which maintain order while allowing efficient insertions and deletions.

What about hash tables? Can they be used for insertion and deletion?

Hash tables are great for fast access and can handle insertions and deletions efficiently, but they don't maintain order.
