/*
   Backward String
   Page 653, # 1

   Write a method that accepts a String object as an argument
   and displays its contents backward. For instance, if the
   string argument is "gravity" the method should display "ytivarg".
   Demonstrate the method in a program that asks the user to input
   a string and then passes it to the method.
