Hackerrank Print in Reverse solution

Problem Statement

This challenge is part of a tutorial track by MyCodeSchool and is accompanied by a video lesson.

You’re 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. The head pointer may be null meaning that the list is empty - in that case, don’t print anything!

Soruce code:

 /*  
  Print elements of a linked list in reverse order as standard output  
  head pointer could be NULL as well for empty list  
  Node is defined as   
  struct Node  
  {  
    int data;  
    struct Node *next;  
  }  
 */  
 void ReversePrint(Node *head)  
 {  
  // This is a "method-only" submission.   
  // You only need to complete this method.   
   int a[100],i=0;  
   while(head!=NULL){  
     a[i] = head->data;  
     i++;  
     head = head->next;  
   }  
   for(int j = i-1;j>=0;j--){  
     cout<<a[j]<<endl;  
   }  
 }
