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.

Sample Output

When that day I hear your voice
I have some special feeling
Let me always think I don't wanna forget you
I remember at the day
You are always on my mind
Eventhough I just can think about you
If the day in the future
This love will becoming true
I've never change my mind that I will love you forever
I don't care how fool it is
I will let my dream come true
I will tell you something I wanna let you know, I let you know

I love you, loving you, as the mouse loves the rice
Even every day has storm, I will always by your side
I miss you, missing you
I don't care how hard it is
I just want you to be happy
Everything, I do it for you
