    Version 0: display digits IN REVERSE ORDER.

    This program prints out from right to left the binary digits 
    of an integer entered by the user at run time.  Because the digits 
    are acquired by integer division using %,  they are easily displayed
    "backwards," i.e., from right to left.  (See the sample I/O at
    the end of this file for examples.)
