Problem Description

This is a true story. A man showed his
love to a girl,but the girl didn't replied clearly ,just gave him a Morse
Code:
****-/*----/----*/****-/****-/*----/---**/*----/****-/*----/-****/***--/****-/*----/----*/**---/-****/**---/**---/***--/--***/****-/
  He was so anxious that he asked for help in the Internet and after one day a
girl named "Pianyi angel" found the secret of this code. She translate this code
as this five steps:
1.First translate the morse code to a number
string:4194418141634192622374
2.Second she cut two number as one group
41 94 41 81 41 63 41 92 62 23 74,according to standard Mobile phone can
get this alphabet:GZGTGOGXNCS

3.Third she change
this alphabet according to the keyboard:QWERTYUIOPASDFGHJKLZXCVBNM =
ABCDEFGHIJKLMNOPQRSTUVWXYZ
So ,we can get OTOEOIOUYVL
4.Fourth,
divide this alphabet to two parts: OTOEOI and OUYVL, compose
again.we will get OOTUOYEVOLI
5.Finally,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,the task is translate the
number strings.

Input

A number string each line(length <= 1000). I ensure
all input are legal.

Output

An upper alphabet string.

Sample Input

4194418141634192622374

41944181416341926223

Sample Output

ILOVEYOUTOO

VOYEUOOTIO
