All you need to do is keep changing head to head->next till head is null, just like I have done below. You need all these variables *current, *prev, *next as you don't have to track the nodes. Using an Array, the size has to be fixed and can not be dynamic. You want to make your ReversePrint more generic, so it wise to use STL Containers i.e vector.In terms of making things cleaner, code does justice. goes through array in reverse order and prints at the end of list, sets head to the last value in linked list which is previous updates link of current.next to value of previous A typical illustration of sequential access. store data into an array to print out later A linked list is a sequential access data structure, where each element can be accesed only in particular order. allocate memory to an array and initialize i=0 current is head because it is starting position while previous is where we want the head to be pointing, which is null, since we are reverse a linked list 2) One by one push all the node addresses to stack. Repeat steps 3 and 4 while the stack is not empty. Move to the next node and pop the top element from the stack, and. Change the values of the nodes from the beginning of the linked list with the top element of the stack. sets current and previous to their respective values. 1) Create an empty stack of type node pointer using Standard Template Library(STL). Push all the values of the nodes from starting into the stack. creates nodes named current, prev, next Head pointer could be NULL as well for empty list ![]() > from collections import deque > deque() deque ( ) The code above will create an empty linked list. You can use the following piece of code to do that with deque: >. Print elements of a linked list in reverse order as standard output However, in this article you’ll only touch on a few of them, mostly for adding or removing elements. We have to create two classes, one class for nodes and the. ![]() Is empty - in that case, do not print anything! /* Advantages over singly linked list 1) A DLL can be traversed in both forward and backward direction. The head pointer may be null meaning that the list Need to print all its elements in reverse order from tail to head, oneĮlement per line. You are given the pointer to the head node of a linked list and you 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: I solved this problem in C++ and was looking for feedback on my code.
