Problem A: Mirror, Mirror
-------------------------
Walking towards his parked car, John was amused to note what appeared to be 
a string of gibberish painted along the front of an emergency vehicle parked 
behind him: ECNALUBMA. It was only after he climbed into his own car and 
glanced into his rear-view mirror that the string suddenly made sense: 
AMBULANCE.

John belatedly realized that even the individual letters had been reversed, 
but that he had mentally corrected these without even being aware of doing 
so.  It was the rearrangement of the letters into an appropriate word that 
had stymied him.  

Fascinated with this idea, John would now like to practice his mirror-reading 
skills. Write a program that accepts input phrases and prints them, reversing 
the order of the characters.

Input
-----
Input consists of one or more lines, each containing from 1 to 80 printable 
ASCII characters (alphabetics, numerals, blanks, and punctuation).
End of input is signaled by a line containing only the string ***.

Output
------
For each line of input data, your program should print a single line of 
output containing the same characters as the input line, in reverse order.

Sample input
------------
AMBULANCE
Evian
madam, i'm adam
***

Sample output
-------------
ECNALUBMA
naivE
mada m'i ,madam
