Node 5's previous pointer points be NULL and next pointer points to Node 4 Node 4's previous pointer points to Node 5 and next pointer points to Node 3 Node 3's previous pointer points to Node 4 and next pointer points to Node 2
Node 2's previous pointer points to Node 3 and next pointer points to Node 1 Node 1's previous pointer should point to Node 2 and next pointer be NULL We need to reverse both the links of every node of the doubly linked list. Node 5's previous pointer should point to Node 4 and next pointer should be NULL Node 4's previous pointer should point to Node 3 and next pointer should point to Node 5 Node 3's previous pointer should point to Node 2 and next pointer should point to Node 4 Node 2's previous pointer should point to Node 1 and next pointer should point to Node 3 Node 1's previous pointer should be NULL and next pointer should point to Node 2
The structure of the doubly linked list also contains a field to store the data of the node. Structure of a doubly linked listĪ double linked list contains two pointers : a pointer to store the address of the next node (same as in singly linked list) and a pointer to store the address of the previous node. In singly linked list, only forward traversal is possible, whereas in doubly linked list, forward and backward traversal is possible. Introduction to Doubly Linked ListĪ doubly linked list is a linear data structure which is a linked list which contains an extra pointer to store the address of the previous node.
#Reverse linked list how to#
In this article, we are going to see how to reverse a doubly linked list by reversing the links of each node (without swapping values of nodes) and have implemented the solution using C++.
