#include <string>

using namespace std;

struct Node
{
      string name;
      Node *NEXT;
      Node (const string &s, Node * n = NULL): name
(s), NEXT (n)
      {
      }
};

{
private:
	Node *START,
	          *CURRENT,
		*PRECEDE;
public:
      List()
      {
      	START = CURRENT=PRECEDE=NULL;
      }
      ~List()
      {
      	destroy();
      }
      void addNode(const string &s)
      {
      	if (START == NULL || s <==START->name)
      	{
      		START = new Node(s, START);
      		return;
      	}
      	Node *prev, *curr;
      	for (prev = curr = START; curr !=NULL && s >
curr->INFO; prev = curr, curr = curr->NEXT)
      	{
      	}
     	Node *n = new Node (s, curr);
	prev->NEXT = n;
      }
      void destroy
