What is Doubly Linked List

By Dinesh Thakur

A more sophisticated kind of linked list is a doubly-linked list or a two-way linked list. In a doubly linked list, each node has two links: one pointing to the previous node and one pointing to the next node.

 Node Structure

Implementation of a doubly linked list

 

Adding an element to the list

 

To add the first node

 

first_node->next = NULL;

first_node->data = input_element;

first_node->prev = NULL;

 

To add a node at the position specified

 

Temp_node = *first_node;

for ( counter = 0 ; counter<position-1 ; counter++ )

{

Temp_node = Temp_node->next;

}

new_node->next = temp_node->next;

temp_node->next->new_node;

new_node->prev = temp_node->next->prev;

temp_node->next->prev = new_node;

 

Deleting a particular element from the list

 

Temp_node = *first_node;

If ( temp_node->data = = input_element )

First_node = first_node->next;

else

{

while ( temp_node != NULL && temp_node->next->data !=

input_element)

temp_node = temp_node -> next;

delete_node=temp_node->next;

temp_node->next=delete_node->next;

delete_node->next->prev=temp_node;

free(delete_node);

}
