 超级大乐透

class BigHappyTicket: public  Ticket
{
public:
 BigHappyTicket(std::string ticket_str);
 BigHappyTicket(){}
 virtual size_t firstLength(){return 5;}
 virtual size_t secondLength(){return 2;}
 virtual boost::shared_ptr  CreateSafeInstance();
 virtual std::vector& getData(boost::shared_ptr ticket);

};

双色球

class Color2Ticket: public  Ticket
{
public:
 Color2Ticket(std::string ticket_str);
 Color2Ticket(){}
 virtual size_t firstLength(){return 6;}
 virtual size_t secondLength(){return 1;}
