Due 2/8/2000
-------------------------------------------------------------------------------

Trace the following loop, using the format shown in lecture:
+ Each assignment statement gets its own column.
+ Draw a long/heavy line each time the loop guard is tested.

(You may try (modifying and) running this code to verify your
answer, but you really should do it by hand *first* to get the
practice.)

    int t;
    int s;
    int triangle;
    t = 5; 
    s = 5;
    while (s<10 && t<10) {
    	triangle = t * (t + 1) / 2;
    	if (triangle == s*s) {
    	    System.out.println
    		(t + "-triangle " + triangle + " == " +
    		s + "-square " + s*s);
    	    t = t + 1;
    	    s = s + 1;
    	} else if (triangle < s*s) 
    	    t = t + 1;
    	else 
    	    s = s + 1;
    }
