我个人觉得这道题，考查的就是对字符串的输入问题的处理。

题目给了一个提示：输入数据量较大，建议采用scanf和printf输入和输出数据。

Description

You have just moved from 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

注意在输入字典数据和查询数据之间有一个空行。（本题的输入关键处理部分）也是我写这篇随笔的用意。
