Crack the Code

Cryptography is the science and technology of coding messages so that only the intended recipient can read them. Cryptanalysis, on the other hand, is the science of breaking the codes. For this problem, assume you're a cryptanalyst hired to break open a series of encrypted messages captured in a police raid to the headquarters of the local mafia. Your colleagues have already reverse engineered the encryption program (see crack.pas or crack.c for the code), and the only thing left to do is to reverse the algorithm and guess the key used to encrypt the files. Along with the encrypted files, there are also some plaintext files that are believed to originate from the same source as the encrypted files and thus have similar structure in terms of language, word usage, etc.

Task

Your task is to decrypt the given messages and save them in the specified files. You do not have to provide any program--just the decrypted messages.

Input

You are given several data sets. Set consists of the files cran.*, where n is the number identifying the data set. Each data set consists of the files:

• cra*.in, encrypted message,
• cra*.txt, plaintext files of the same origin, as the encrypted message.

Output

For each encrypted message cra*.in, you should save the decrypted message in the file cra*.out.
