B - Babelfish

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 100,000 dictionary entries, followed by a blank line, followed by a message of up to 100,000 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 sequence of at most 10 lowercase letters.

Output

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

Sample Input

dog ogday

cat atcay

pig igpay

froot ootfray

loops oopslay

 

atcay

ittenkay

oopslay

Sample Output

cat

eh

loops

Hint

Huge input and output,scanf and printf are recommended.

 

 

 

#include<stdio.h>

#include<cstdio>

#include<string.h>

#include<cstring>

#include<map>

#include<iostream>

using namespace std;

char s[100],a[100],b[100];

map<string,string>c;

int main()

{

    while(gets(s)&&s[0]!='\0')

    {

        sscanf(s,"%s%s",a,b);

        c[b]=a;

    }

    while(gets(b))

    {

        if(c.find(b)==c.end())

            cout<<"eh"<<endl;

        else

            cout<<c[b]<<endl;

    }

    return 0;

}

 

 

G++提交。

 

注意中间空行读取时s[0]=0,这是因为gets在读取完一行后跳过\n但并未保存\n，所以s[0]=’\0=0。’
