题目大意：

输入两个人的属相，并且第一个人一定比第二个人岁数大，问你这两个人至少差多少岁。

代码：

#include<bits/stdc++.h>using namespace std;//rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog and pig.int f(char *s){    if(s[0]=='r'&&s[1]=='a'&&s[2]=='t')return 1;    if(s[0]=='o')return 2;    if(s[0]=='t')return 3;    if(s[0]=='r'&&s[1]=='a'&&s[2]=='b')return 4;    if(s[0]=='d'&&s[1]=='r')return 5;    if(s[0]=='s'&&s[1]=='n')return 6;    if(s[0]=='h')return 7;    if(s[0]=='s'&&s[1]=='h')return 8;    if(s[0]=='m')return 9;    if(s[0]=='r'&&s[1]=='o')return 10;    if(s[0]=='d'&&s[1]=='o')return 11;    return 12;}char a[1000],b[1000];int main(){    int t;    scanf("%d",&t);    while(t--)    {        scanf("%s%s",a,b);        int aa=f(a);int bb=f(b);        int ans;        if(aa-bb>0)ans=12-(aa-bb);        else if(aa-bb<0)ans=bb-aa;        else ans=12;        printf("%d\n",ans);    }}
