(Solved) : Alter Block Code Single Linked List Double Linked List C Programming Include Define Node S Q26674487 . . . .

How do i alter this block of code from single linked list todouble linked list in c programming?

#include<stdio.h>
//Define the node structure that has 2 members – int variable and apointer variable
struct Node
{
   int data;
   struct Node *next;
};
int main()
{
   //Declare and initialise 5 pointer nodes
   struct Node *nOne = (struct Node*)malloc(sizeof(struct Node));
   struct Node *nTwo = (struct Node*)malloc(sizeof(struct Node));
   struct Node *nThree = (struct Node*)malloc(sizeof(struct Node));
   struct Node *nFour = (struct Node*)malloc(sizeof(struct Node));
   struct Node *nFive = (struct Node*)malloc(sizeof(struct Node));

   //Need a head node and it is pointing to the firstnode called nOne
   struct Node *head = nOne;

   //Assign different values
