使用map和isstream，轻松搞定。郁闷的是，我把”eh” 输成了”en”调了半天没有找到错误，这下ac的ratio又被拉低了……

#include<iostream>
#include<map>
#include<string>
#include<sstream>
using namespace std;
int main()
{
  string dic;
  map<string, string> m;
  while(getline(cin, dic) && dic != "")
  {
    istringstream is(dic);
    string key,value;
    is>>value>>key;
    m[key] = value;
  }
  string fatMouse;
  while(cin>>fatMouse)
  {
    if(m.find(fatMouse) != m.end())
    {
      cout<<m[fatMouse];
    }
    else
    {
      cout<<"eh";
    }
    cout<<endl;
  }
}
