Simple Cipher

Problem Description

Julius Caesar once used a very simple cipher. For each character in the plaintext, replace it with the character that is 55 positions later in the alphabet, obtaining the ciphertext. For example, the letter A is replaced by F. The correspondence between ciphertext and plaintext characters is shown below.

Ciphertext:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Plaintext:

V W X Y Z A B C D E F G H I J K L M N O P Q R S T U

Your task is to decrypt a given ciphertext into the plaintext.

Note that all letters appearing in the ciphertext are uppercase letters. The ciphertext may also contain non-alphabetic characters; these characters are not to be decoded.

Input Format

One line giving the ciphertext. The ciphertext is non-empty and contains no more than 200200 characters.

Output Format

Output one line: the plaintext corresponding to the ciphertext.
