Description

After Gardon had got Angel‘s letter, he found it was encoded...Oh my god, why did she encode a love-letter?? But don‘t worry, she wrote the algorithm for encoding after the letter:
Each charactor are changed to a corresponding charactor. If the keyword is "Angel", the rule will be:

ABCDEFGHIJKLMNOPQRSTUVWXYZ
ANGELZYXWVUTSRQPOMKJIHFDCB

You may find that in the bottom line, charactors of the keyword come first. All other charactors will come in a reversed order.

Now given another keyword, work the letter out!
Can you write a program to translate the letter?
 

Input

The letter will begin with the keyword (All uppercase), then lines of text.
 

Output

Decode the letter and print it out. Please note that a upper-case charactor will be decoded to a upper-case charactor, while a lower-case charactor will be decoded to a lower-case charactor.
