题目描述

注：本题目自由设计，但必须使用类进行代码设计。

世界杯32支参赛队分为八个小组,每个小组分别有四支球队进行比赛，每支球队都必须和其他三支球队进行且只进行一场比赛,每组4个队循环比赛，共打6场(a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4),每场比赛90分钟，胜平负分别积3、1、0分。每个小组积分的前两名球队出线进入淘汰赛阶段的1/8决赛，共16支队，即“16强”。

每个小组分别有四只球队，其排名按以下规则确定：
a、积分高者排名靠前
b、小组中总净胜球高者排名靠前
c、小组中总进球数高者排名靠前
d、不能确定
净胜球数是指进球数（正数）与失球数（正数）的差。
如，红队胜黄队4：2，蓝队胜黄队3：1，红队负蓝队2：3
红队进6球，失5球，净胜球数为：6-5=1
黄队进3球，失7球，净胜球数为：3-7=-4
蓝队进6球，失3球，净胜球数为：6-3=3
//以下是可供参考的代码
#include <stdio.h>
#include <iostream>
#include <string>
using namespace std;

class FootballGroup
{
private:
    int score[4]; //总积分
    int goaldiff[4]; //总净胜球
    int totalgoals[4]; //总进球数
    string teamname[4] ; //球队的名称
public:
    FootballGroup()
    {
        for(int i=0; i<4; i++)
        {
            score[i]=goaldiff[i]=totalgoals[i]=0;
        }
    }
    void setTeamName(int teamindex,string name)  //设置第teamindex+1个队的队名
    {
        teamname[teamindex] = name;
    }
    void addMatchresult(int teamindex1,int teamindex2,int score1,int score2);
    void showResult();
};
int main()
{
    FootballGroup GroupA;
    string name;
    int i,j;
    for(i=0; i<4; i++)
    {
        cin>>name;
        GroupA.setTeamName(i,name); //球队a1,a2,a3,a4的名称
    }
    int score1,score2;
    for(i=0; i<3; i++) //a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4
        for(j=i+1; j<4; j++)
        {
            cin>>score1>>score2; //两队的比分
            GroupA.addMatchresult(i,j,score1,score2);
        }
    GroupA.showResult();
    return 0;
}

输入

第一行 4个参赛队伍的名称
第二行开始到第七行，6场比赛的比分(a1-a2;a1-a3;a1-a4;a2-a3;a2-a4;a3-a4)

输出

进入淘汰赛阶段的两只球队，如果不能确定，则输出"NO"

样例输入

a1 a2 a3 a4
1 2
0 0
2 3
3 1
2 2
1 2

样例输出

a2 a4
