Description:
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 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".
dog ogday
cat atcay
pig igpay
froot ootfray
loops oopslay
atcay
ittenkay
oopslay
Sample Output:
cat
eh
loops
這個題的大意是讓你建立一個字典,然後不知道從哪行開始給你單個詞,讓你把奇怪的詞轉換成明文。
由於有map容器,建立映射的部分會極其簡單,所以這個題的難點是字符串的操作。需要注意的是在明文與暗文間會有一行空白的行,所以我們的任務就剩下拆分字串了。
