9. Python program to insert a new node at the end of the Circular Linked List
In this program, we will create a circular linked list and insert every new node at the end of the list. If the list is empty, then head and tail will point to the newly added node. If the list is not empty, the newly added node will become the new tail of the list. The previous tail will point to new node as its next node. Since it is a circular linked list; the new tail will point to head. In other words, the new node will become the last node (tail) of the list, and the previous tail will be the second last node.
After inserting the new node to the end of the list
New represents the newly added node. D is the previous tail. When new is added to the end of the list, it will become new tail and D will point to new.
a. display() will show all the nodes present in the list.
