Ans. 
Operations on Linked List and Array with their time complexities.
• Linked List operations: insertion (O(1)), deletion (O(1)), traversal (O(n)), search (O(n))

• Array operations: insertion (O(n)), deletion (O(n)), traversal (O(n)), search (O(n))

• Arrays have constant time access to elements while linked lists don't.
