 // "Binary numbers" are a way to represent integers as a sequence of 
 // zeros and ones. Write a program to convert a number x (between
 // 0 and 1023) into a 10-bit binary number, as follows:
 // Begin with b=512. If x is larger than or equal to 512, output a 1 and
 // subtract 512 from the number. Otherwise output a 0 and don't
 // change the number. Then do the same using b=256. Then do the
 // same using b=128. Each time, b is cut in half. Keep repeating
 // until (and including) b=1. When b=0, stop and don't print any
 // more results. For example, if the user inputs 152 for x, then:
 // 152 is less than 512, so first print a zero.
 // 152 is greater than or equal to 128, so print 1, set x=24 (which is 152-128).
 // 24 is less than 64, so print 0.
 // 24 is less than 32, so print 0.
 // 24 is greater than or equal to 16, so print 1, set x=8 (which is 24-16).
 // 8 is greater than or equal to 8, so print 1, set x=0 (which is 8-8).
 // 0 is less than 4, so print 0.
 // 0 is less than 2, so print 0.
 // 0 is less than 1, so print 0.
 // In all, the program should have printed "010011000". You can check
 // your work by searching onlie for "0b010011000 in decimal" to make
 // sure you get the same number the user started with.

 System.out.print("Enter a decimal number (0 to 1023): ");
