本题因为题意说肯定能够称出来，所以不用担心他是怎么称的，只要对几种情况进行穷举即可
代码：
1 #include<stdio.h>
2 #include<string.h>
3 char a[5][10],b[5][10],c[5][10];
4 int islight(char x)
5 {
6 int i;
7 for(i=1;i<=3;i++)
8 {
9 switch(c[i][0])
10 {
11 case 'u':if(strchr(b[i],x)==NULL) return 0;break;
12 case 'e':if(strchr(a[i],x)!=NULL||strchr(b[i],x)!=NULL) return 0;break;
13 case 'd':if(strchr(a[i],x)==NULL) return 0;break;
14 }
15 }
16 return 1;
17 }
18 int isheavy(char x)
19 {
20 int i;
21 for(i=1;i<=3;i++)
