You have just moved from Waterloo to a big city. The people here speak an incomprehensible dialect of a foreign language. Fortunately, you have a dictionary to help you understand them.

Input

Input consists of up to 100000100000 dictionary entries, followed by a blank line, followed by a message of up to 100000100000 words. Each dictionary entry is a line containing an English word, followed by a space and a foreign language word. No foreign word appears more than once in the dictionary. The message is a sequence of words in the foreign language, one word on each line. Each word in the input is a non-empty sequence of at most 1010lowercase letters.

Output

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

dog ogday

cat atcay

pig igpay

froot ootfray

loops oopslay

atcay

ittenkay

oopslay

cat

eh

loops

题意

前面那部分是字典里的，后面就查找给出的字符串有没有属于前面的字典里，有的话就输出那个单词

思路

用map存就行了

代码

#include<bits/stdc++.h>

using namespace std;

map<string,string> m;

int main(){

    string line,a,b;

    while(getline(cin,line)&&line!=""){

        stringstream s(line);//格式转换

        s>>a;

        s>>b;

        m[b]=a;

    }

    while(cin>>b){

        a=m[b];

        cout<<(a==""?"eh":a)<<endl;

    }

}
