Given a linked list, print reverse of it using a recursive function. Technique 1 In this way, a new linked list will be created and all the items of the first linked list will be added to the new linked list in reverse order. This tutorial will explain more about circular linked list which is a collection of nodes in which the nodes are connected to each other to form a circle. When sub linked list get printed in reverse order then we will print the head node stored in function stack. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. reverse() will print the circular linked list in reverse order. Python Code: The function also visits every node of linked list only once. Same principle can be applied by using recursion. But with home work I suspect they don't have much choice. Reverse a Doubly linked list using recursion. Final Output 1 2 3 4 5 6. Now how to print a singly linked list in reverse order. Now, one by one, we can start printing the nodes in reverse order using a stack starting from the last chunk. This program makes each data element to link to its predecessor. Reverse a circular linked list. Recursively call reverse() by considering node next to current node and prints out all the nodes in reverse order starting from the tail. close, link For this, we should have knowledge of length of list. 5th Iteration _ 2 3 4 5 6 We have to print a Linked List in Reverse order. Time Complexity: O(n) We can also swap data instead of pointers to reverse the Doubly Linked List. Attention reader! Reverse a Linked List according to its Size. a. reverse () will print the circular linked list in reverse order. code. I'm not sure if storing the data in an array and looping through it in reverse and printing was the right approach since this challenge was to use linked lists, but I didn't know how else to do it: You are given the pointer to the head node of a linked list and you need to print all its elements in reverse order from tail to head, one element per line. Write a C program to create a singly linked list of n nodes and reverse the order of nodes of the given linked list. Printing the list (Backward) Printing the list backward is tricky because we cannot move backward in a singly linked list. This article is contributed by Shivam Pradhan (anuj_charm). What we can do is next point. in C Programming Language. 1.) swap(curr); // update the previous node before moving to the next node. 13, Jul 17. 1st Iteration _ _ _ _ _ 6 PrintReverseLinkedList Class: PrintReverseLinkedList class is responsible for printing single linked list in reverse order. generate link and share the link here. To reverse the list itself see this Difficulty Level: Rookie, edit Program – print single linked list in reverse order using recursive algorithm. For printing a list in reverse order, we have already discussed Iterative and Recursive Methods to Reverse. Method used for reversing array can be used to swap data. This method checks whether next node to current is head which implies that, current is pointing to tail, then it will print the data of the tail node. brightness_4 Reverse a Linked List according to its Size, Data Structures and Algorithms – Self Paced Course, Ad-Free Experience – GeeksforGeeks Premium, We use cookies to ensure you have the best browsing experience on our website. struct Node* curr = *headRef; // traverse the list. Don’t stop learning now. We will store the head node of linked list in function stack and then recursively call reverseLLPrint function for sub linked list starting from head->next. Given a circular linked list of size n.The problem is to reverse the given circular linked list by changing links between the nodes. In this example, we will create a java program of circular linked list, then traverse the list in the reverse order and print the nodes. Find code solutions to questions for lab practicals and assignments. Trick : Idea behind printing a list in reverse order without any recursive function or loop is to use Carriage return (“r”).

Now, we should print n-1 blanck space and then print 1st element then “r”, futher again n-2 blank space and 2nd node then “r” and so on.. Experience. For example, if the given linked list is 1->2->3->4, then output should be 4->3->2->1.Note that the question is only about printing the reverse. Experience. 12, Jun 18. The method descendingIterator() returns an Iterator object with reverse order. Here is the source code of the C Program to Print linked list in reverse order using recursion. Circular linked lists can be traversed from anywhere (given any node) in the list, which gives flexibility and it also enahnces efficiencies of some operations however it complicates operations by inducing special cases to deal with circularity of list Required knowledge Basic C programming, Functions, Singly Linked List, Dynamic memory allocation Algorithm … Continue reading C program to reverse a Singly Linked List → We can just use loops but if we are asked to write a program to print the linked list without actually reversing it, we can not do it by just using loops. acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Stack Data Structure (Introduction and Program), Doubly Linked List | Set 1 (Introduction and Insertion), Delete a Linked List node at a given position, Function to check if a singly linked list is palindrome, Implement a stack using singly linked list, Find Length of a Linked List (Iterative and Recursive), Program for n'th node from the end of a Linked List, Reverse a Linked List in groups of given size | Set 1, Write a function to get the intersection point of two Linked Lists, Implementing a Linked List in Java using Class, Circular Linked List | Set 1 (Introduction and Applications), Search an element in a Linked List (Iterative and Recursive), Remove duplicates from a sorted linked list, Add two numbers represented by linked lists | Set 1, Remove duplicates from an unsorted linked list, Write a function to get Nth node in a Linked List, Swap nodes in a linked list without swapping data, Iterative and Recursive Methods to Reverse, Shuffle 2n integers in format {a1, b1, a2, b2, a3, b3, ......, an, bn} without using extra space, Count words that appear exactly two times in an array of words, Given a linked list which is sorted, how will you insert in sorted way, Insert a node at a specific position in a linked list, Add two numbers represented by linked lists | Set 2, Clone a linked list with next and random pointer | Set 1, Applications of linked list data structure, Write Interview In this post, an interesting method is discussed, that doesn’t require recursion and does no modifications to list.

Of course, I hate single linked lists, because they're a pain to use compared to double linked lists. This method checks whether next node to current is head which implies that, current is pointing to tail, then it … Input : 6 5 4 3 2 1 prev = curr; // move to the next node in the doubly linked list. If a Stack was available, we could traverse in order, and push elements to the Stack. Carriage return (“r”) : It commands a printer (cursor or the display of a system console), to move the position of the cursor to the first position on the same line.

I'd use the recursive method, because looping to print a list in reverse order is too much of a pain to be worth the effort. Get hold of all the important DSA concepts with the DSA Self Paced Course at a student-friendly price and become industry ready. By iterating through it, you can get the elements in the reverse order. Then we can create a temp array of the same size which will store the heads of each chunk of root(n). Algorithm to reverse a doubly linked list. STEP 2: When you reach null, return. Examples: INPUT: // swap next and prev pointers for the current node. generate link and share the link here. For example, if the given linked list is 1->2->3->4, then output should be 4->3->2->1.

For this, we should have knowledge of length of list. Don’t stop learning now. NOTE:Above program may not work on online compiler because they do not support anything like carriage return on their console. Last Updated : 14 Oct, 2020. This means instead of setting the next pointer of the last node to null, it is linked to the first node. Trick : Idea behind printing a list in reverse order without any recursive function or loop is to use Carriage return (“r”). while (curr != NULL) {.
