Write a program to swap the second node from the head node to the second node from the tail node in linked list. The singly linked list allows only forward iteration and does not support backward iteration.
Print the list of items: 1->2->3->4->5->6->7->8->NULL Print the list of items after pairwise Swap: 1->7->3->4->5->6->2->8->NULL
