To create a demo we have to construct a linked list and this The iterative implementation of reversing a linked list in c++ follows:. And then increment the previous node to the current node and then the current node to the temp node.Īnd then we finally return the head node. We assign the temp node to the next of the current node and then reverse the link by assign the current->next to the previous node. Step 3: While iterating, we perform the following operations: Step 2: Using a while loop we will traverse the linked list once until the next pointer does not become NULL. Step 1: Define three nodes one with the reference to the head node and name it current, and name the other two nodes temp and prev pointers as NULL. We will create a function to reverse the linked list taking reference to the head node and as the only argument and return the head of the new linked list: And if there are two or more elements, then we can implement an iterative solution using three-pointers If the linked list has only one or no element, then we return the current list as it is. Now that you have tried solving the problem yourself given the two types of approaches to solving this problem, let’s discuss both the approaches one by one: Iterative Solution for Reversing a Linked List Or, think of a recursive approach to find the reversed list in a single pass.Think of an iterative approach to find the reversed list in a single pass.There can be two approaches to solve this problem, the following are the hints, try solving the problem by yourself and then head over to the next section to find the solution and C++ code. 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.
#RECURSIVE LINKED LIST STACK HOW TO#
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.
