printRange

Write a method printRange that takes two integers
   as parameters, a low and a high, and that prints out all integers in the
   range from low to high inclusive inside square brackets and separated by
   commas.  For example, the call:

        printRange(5, 10);

   should produce the following output:

        [5,6,7,8,9,10]

   Your method should produce a complete line of output.  If low and high are
   equal, the output should be a list with just one number.  If low is larger
   than high, the output should be an empty list (with just the square
   brackets).  Your method should also work properly for negative integers.
   For example, the following series of calls:

        printRange(3, 3);
        printRange(10, 1);
        printRange(-10, -5);
	printRange(-5,-10);

   should produce the following four lines of output:

        [3]
        []
        [-10,-9,-8,-7,-6,-5]
        []
