题目链接：URAL 1804 The Machinegunners in a Playoff

题意：给出M队上一场（主场或客场）得分和失分（对方进球），求下一场M队的比赛策略

比赛的规则：2场比赛，两队分别依次主场。1.总分大的胜利。2.总分相同，客场得分多的胜利。3.两者都相同，两队都有可能获胜。每队一场得分不超过30分

策略：1.M队可能晋级的最小分数，2.M队使C队可能晋级的最大分数。

思路：求最小：C队得分0。求最大：C队得分30分。关键是比较每次两队的客场得分。

AC代码：

#include<stdio.h>
#include<string.h>
int main()
{
	int a,b;
	int t,i,min,max;
	char s[10][100];

	while(scanf("%d",&t)!=EOF)
	{
		while(t--)
		{
			scanf("%s%s%s%s%s%s %d %s%s%s %d %s",s[0],s[1],s[2],s[3],s[4],s[5],&a,s[6],s[7],s[8],&b,s[9]);
			if(strcmp(s[3],"home")==0)//Machinegunners主场
			{
				//a+x=b
				min=b-a;//总球数相同 M客场进min球 C客场进b球
				if(min>=0 && min<b)
					min++;
				else if(min<0)
					min=0;
				//a+max=b+30
				max=30+b-a;//总球数相同 M客场进max球 C客场进b球
				if(max<=30 && max>b)
					max--;
				else if(max>30)
					max=30;
			}
			else
			{
				min=b-a;//总球数相同 M客场进a球 C客场进0球
				if(min>=0 && a<0)
					min++;
				else if(min<0)
					min=0;

				//a+max=b+30
				max=30+b-a;
				if(max<=30 && a>30)
					max--;
				else if(max>30)
					max=30;
			}
			printf("%d %d\n",min,max);
		}
	}

return 0;
}
