 * Description:
 * Write a program that prints the numbers from 1 to 100 [including 100]. But
 * for multiples of three print "Fizz" instead of the number and
 * for the multiples of five print "Buzz" [instead of the number].
 * For numbers which are multiples of both three and five print "FizzBuzz" [instead of the number].
