(4)  3. Modify the MAL sorting program on page 222 (pg 212 in old edition)
        to do the following:**
        (a) prompt for up to 20 positive (>0) integers to
            be entered, with zero or a negative number used to end the input;
        (b) store these integers in the array 'ar';
        (c) sort the integers into DESCENDING order (largest first);

(3)  5. Write a MAL procedure called 'factorial' which calculates 
	N factorial for a positive integer N.  Pass the value of 
	N in $a0 ($4) and return the value of N! in $v0 ($2).  Test 
	your procedure with the main program exactly as given below:**

	__start:	geti $4
			jal factorial
			move $9, $2
			puti $9
			done
