Singly-linked doubly-linked and circularly-linked lists

Question

Illustrates the singly-linked doubly-linked and circularly-linked lists?

Answer 1

The difference in all is how many pointers all nodes have, and what they are pointing to. A linked list is contained of "Nodes" each node has data and also 1 or more pointers. But singly linked lists consist of one pointer per node, and a twice as linked list has 2 pointers per node. Several programs use several pointers per node. The reason of these pointers is to hold the list together. Within a single linked list, you can view a node and can after that move upon to the next node that this is pointing to till you've passed by them all. A doubly-linked list would have a pointer to the subsequent node and also to the previous node. Therefore you can move forward and backward by the list. But a circularly-linked list doesn't essentially have a set number of pointers since it simply means that the final node points to the first node making a big circle. But,  a non-circularly-linked list would not have this last to first pointer and therefore you would in the end reach the end of the list and stop.
