Doubly linked list
Nodes in a doubly linked list are linked in both directions using next and previous pointer. Two consecutive elements are linked by previous and next pointer. Thus it is possible to traverse any direction from head to tail or from tail to head. The limitation of single linked list thus has been eliminated and most of the practical and applied list has this type of structure inside it. Find the visual representation of the doubly linked list in the below figure.
