$2-$ Extend the class linkedListType by adding the following operations:

a$.$ Write a function that returns the info of the kth element of the

linked list. If no such element exists, terminate the program.

b$.$ Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program.

Provide the definitions of these functions in the class linkedListType. Also, write a program to test these functions. $($Use either the class unorderedLinkedList or the class orderedLinkedList to test your function.$)$

Use c$++.$
