Good code is its own best documentation. As you are about to add a comment, ask yourself, How can I improve the code so that this comment isn't needed? Improve the code and then document it to make it even clearer. Steve McConnell
Circular linked list last node point to the first node of linked list. The single linked list last node point to null value which uses to identify the end of linked list. But, the circular linked list tail node point to the head node. A circularly linked list node looks exactly the same as a linear singly linked list.
Write a program to implement circular linked list. Once the item moved to tail, it overrides the head items.
Insert items in the circular linked list: 41, 25, 63, 84 41->25->63->84 Insert item at 2nd position: 10 41->25->10->63->84 Insert item in the circular linked list: 53, 12 41->25->10->63->84->53->12 Delete the item in the position 1:25 Linked List items: 41->10->63->84->53->12
