It returns the location of the item in the list, if the item is found. To compare each node data with the item to be searched. To remove a node which is present just after the node containing the given data. To remove a node from the end of a linked list. To remove a node from the beginning of a linked list. To add a node in a linked list after the specified node. To add a node at the end of a linked list. To add a node at the beginning of a linked list. The other operations of the doubly linked list are described below. Operations on a doubly-linked list: Node Creation: But, since the list maintains pointers in both the directions i.e., both forward and backwards, we can easily manipulate the elements of the list. Memory Representation of a doubly-linked list:Ī doubly linked list causes more expansive basic operations such as insertion and deletion because it consumes more space for every node. Hence, we can use the previous address stored inside the previous part of each node to find the details about the previous node. To overcome this limitation of a singly linked list, each node of the doubly linked list contains the address of its previous node. Thus, we can traverse only in one direction, in a singly linked list.
In a singly linked list, each node contains the address of the next node but doesn’t have any record of its previous nodes. The null indicating end in each direction is included in the prev part of the first node and the next part of the last node always.
