美食节之破译密码得玩偶

描述

There are many interesting things  more than just a lot of food in the Food Festival, such as code-breaking game that Pianyi angel likes playing. Pianyi angel can get one of a kind dolls if she successfully translated the given password into a correct text as the following steps: 

1.The given password is a number string:4194418141634192622374

2.Cut two number as one group 41 94 41 81 41 63 41 92 62 23 74, according to standard Mobile phone. We can get this alphabet:GZGTGOGXNCS

3.Change this alphabet according to the keyboard: QWERTYUIOPASDFGHJKLZXCVBNM = ABCDEFGHIJKLMNOPQRSTUVWXYZ
So ,we can get OTOEOIOUYVL

4.Divide this alphabet to two parts: OTOEOI and OUYVL, compose again.we will get OOTUOYEVOLI

5.Reverse this alphabet the answer will appear : I LOVE YOU TOO

I guess you might worship Pianyi angel as me,so let's Orz her. Now, your task is to translate more number strings.

输入

The input consists of one or more test cases. Each test case consists of a number string(length <= 1000) per line. We ensure all input are legal.

输出

For each test case, output an upper alphabet string per line.
