Answer Posted / ashutosh
List *nodes[10]; //asked 10th last, so, only 10 items
int pos = 0;
List *ptr = &FirstNode
while(ptr)
{
nodes[(pos%10)] = ptr;
pos++;
ptr = ptr->next;
}
if(pos>=10)
{
printf("Tenth last element is %d",nodes[(pos-10)%10]->data);
}
else
{
printf("There doesn't exist any 1oth last element");
}
