struct node
{
int data;
struct node *ptr;
};


struct node mid_element(struct node* head)//since we pass addr
{
int count=0,n_count,i=0;
struct node* temp,*mid;
temp=mid=head;
while(temp -> ptr != NULL)
{
count++;
temp = temp->otr;
}
count++;

if(count % 2)
{
n_count = (count/2)+1;
for(i=0 ; i<n_count ; i++)
mid = mid -> ptr;
}

return mid;
}
