Solution

The best method for reversing a singly linked list in place (changing an existing list) is c) Using an iterative approach with three pointers (prev, curr, next).

Here's why:

a) Using a stack to store the nodes and then rebuilding the list: This method requires extra space to store the nodes in a stack, which is not efficient.

b) Using recursion to reverse the list: This method can lead to a stack overflow if the list is too long, because each recursive call adds a layer to the system call stack.

c) Using an iterative approach with three pointers (prev, curr, next): This method does not require extra space and will not cause a stack overflow. It simply involves changing the pointers of each node to point to the previous node.

d) Creating a new reversed list and copying the nodes from the original list: This method is not in place because it requires extra space to create a new list.

Write a C program to reverse a single linked list recursively. #include <stdio.h> #include <stdlib.h> struct Node { int data; struct Node* next; }; // Write a function to create a new node with the given data // Write a function to print the linked list // Write a function to reverse the linked list recursively // Write your main function here

The following function reverse() is supposed to reverse a singly linked list. There is one line missing at the end of the function./* Link list node */struct node{    int data;    struct node* next;};  /* head_ref is a double pointer which points to head (or start) pointer   of linked list */static void reverse(struct node** head_ref){    struct node* prev   = NULL;    struct node* current = *head_ref;    struct node* next;    while (current != NULL)    {        next  = current->next;          current->next = prev;           prev = current;        current = next;    }    /*ADD A STATEMENT HERE*/}  What should be added in place of “/*ADD A STATEMENT HERE*/”, so that the function correctly reverses a linked list.*head_ref = prev;*head_ref = current;*head_ref = next;head_ref = NULL;
