  • ZOJ Problem Set–1109 Language of FatMouse

    Time Limit: 10 Seconds      Memory Limit: 32768 KB


    We all know that FatMouse doesn't speak English. But now he has to be prepared since our nation will join WTO soon. Thanks to Turing we have computers to help him.

    Input Specification

    Input consists of up to 100,005 dictionary entries, followed by a blank line, followed by a message of up to 100,005 words. Each dictionary entry is a line containing an English word, followed by a space and a FatMouse word. No FatMouse word appears more than once in the dictionary. The message is a sequence of words in the language of FatMouse, one word on each line. Each word in the input is a sequence of at most 10 lowercase letters.

    Output Specification

    Output is the message translated to English, one word per line. FatMouse words not in the dictionary should be translated as "eh".

    loops oopslay

    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;
    
      }
    
    }
