Output

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

Sample Input

dog ogdaycat atcaypig igpayfroot ootfrayloops oopslayatcayittenkayoopslay

Sample output

catehloops

Hint

Huge input and output, scanf and printf are recommended.

General question:

Enter a dictionary. The dictionary format is a one-to-one ing relationship between English and foreign languages.

Then input several foreign language words and output their English translation words. If the word does not exist in the dictionary, output "eh"

 

Solution:

During input, map is used to create a ing of "foreign language English". During output, the corresponding translation is directly searched through the input characters. If the corresponding string length is 0, output eh. Otherwise, output the corresponding string

In addition, pay attention to the handling of empty rows.
