In this problem statement we are provided with the pointer or reference to the head of a singly linked list, invert the list, and return the pointer or reference to the head of the new reversed linked list.įor example, consider the following linked list:Īfter reversing the complete linked list we return the pointer to the new linked list as demonstrated in the figure: Reversing the list implies reversing all the elements and we can do it by reversing all the links and make the next pointer point to the previous node. Head − A Linked List contains the pointer to the first link called a head pointer. Next − Every node of a linked list contains a link to the next link that is Next. Node − Each node stores data which is called an element. There are three components of a linked list:
The linked list is the second most utilized data structure after arrays. Each link which is a pointer contains a connection to another node.
The general definition is that a linked list is a sequence of data structures, the nodes are connected with pointers, and the last node points to NULL.Ī linked list is a sequence of links that contain elements connected using pointers.

Knowing all this in this tutorial we are going to discuss the basic understanding of a linked list, and implement and analyze how to reverse a linked list in C++. We use linked lists to maintain a directory of names, dynamic allocation of memory, and create an implementation of essentials data structures like stacks and queues, and what not?
Many of you must be familiar with the application of a linked list in the real world and its importance.
