Using linked list stack to reverse3/1/2024 Think about what “flipping the arrows” would mean and make sure you keep track of any temporary variables you might need to hang onto while “flipping” through the list. This blog covered the various methods of reversing a stack. The last node of the list contains a pointer to the null. A node in the linked list contains two parts, i.e., first is the data part and second is the address part. Linked list can be defined as the nodes that are randomly stored in the memory. You just gotta go through and flip the direction of all the yellow and blue arrows (and flip the green and red arrows to point to their counterpart). Linked list is a linear data structure that includes a series of connected nodes. Imagine it were a line of beans with arrows pointing from one bean to the next (in yellow) and previous (in blue) with a special green arrow pointing to the first bean and a special red arrow pointing to the last bean. You need one or two temporary variables max, but nothing more. Using this method, we can access the last inserted. So that the head node will always point the last inserted data. Reversing a doubly linked list is quite straightforward so there is no need whatsoever to leverage an array like this. We should create the linked in reverse order. Step 2: Update the Head pointer using the value of the last node of the list. Step 1: Keep the values of the nodes in the stack until all the values of the nodes are entered. It works, but I would never hire someone who could not do better. The following are the steps used when one does the reversal of the linked list using stack. Write a C++ program to reverse the elements of a stack (using a linked list). If I saw that answer in an interview I would be disappointed because you needed to create an auxiliary data structure that was a complete copy of all of the data in your existing data structure you were operating on (so any time that method is called it allocates O(n) space).
