 * string comparison
 *
 *    Utility to help students understand string comparison
 *
 *    Usage:
 *	     % java compare a1 b1 a2 b2 a3 b3 ...
 *
 *    	    The program will print the results of comparing
 *	    the stringsl a_i to b_i (i=1, 2, 3, ...).
 *    Note:
 *	   s1.compareTo(s2) returns    0   if s1 = s2
 *	   			     < 0   if s1 < s2
 *	   			     > 0   if s1 < s2
