Write the code to reverse the linklist.

Non-Recursive
========

void reverse(struct node ** head)
{
struct node* prev = NULL;
struct node* current = *head;
struct node* next;
while (current != NULL)
{
next = current->next;
current->next = prev;
prev = current;
current = next;
}
}
there are three pointer ( prev, current, next)
next = current*
current* = prev
prev = current
current = next

if we see from above logic then before = is like top to bottom then bottom to top .
* marked pointer will have next.

Recursive
=======

struct node * recLinkedList(struct node *head, struct node *prev)
{
struct node *tmp = head->next;
if ( tmp != NULL)

}

int main()
{
}
