Description

During the transmission of intelligence, to prevent interception, the information often needs to be encrypted in some way. Although simple encryption algorithms may not completely avoid decryption, they can still prevent the information from being easily recognized.

We provide a simplest encryption method: for a given string, replace each letter from a-y or A-Y with its successor letter, replace z and Z with a and A respectively, and leave other non-alphabetic characters unchanged. This will produce a simple encrypted string.

Input Format

Input one line containing a string with a length of fewer than 80 characters.

Output Format

Output the encrypted string for each input line.
