算法：
Map,思想是调用map，定义map<string,string> M
代码：
#include <iostream>
#include <map>
#include <cstdio>
#include <string>
#include <cstring>
using namespace std;
map<string,string> M;
int main()
{
char a[12],b[12],str[30];
while(gets(str))
{
if(strcmp(str,"")==0)break;
int i,l=strlen(str);
for(i=0;i<l;++i)
{
if(str[i]==' ')break;
}
strncpy(a,str,i);
a[i]='\0';
strncpy(b,str+i+1,l-i);
b[l-i]='\0';
// cout<<a<<endl<<b<<endl;
M[b]=a;
}
while(cin>>b)
{
if(M[b]=="")
{
cout<<"eh"<<endl;
}
else
{
cout<<M[b]<<endl;
}
}
return 0;
}
