实现集合的交和并集

	public:

//	private:

		CircListNode<Type>* link;
		
};
template<class Type>class CircList
{
	public:
		CircList()

			current=NULL;
		}
	//	~CircList();
		Type GetData1() {return current->data1;}
		Type GetData2() {return current->data2;}
		void Firster() {current=first;}
		void Next() { current=current->link;}
		void Insert(const Type & value);
		void Josephus(int n,int m);
		void Remove();
