I am sorry. It was not my purpose to offend anybody,  *sincerely*. If I 
might have been understood in such a way, I apologize.
But, Brent, please : there was no question to answer. Jorge M. said: "I 
need a clue...".  I gave him, indirectly.
I responded thus after having read the answers by Albert Lai, OK, but 
short, probably worth completing, and the second one, by Francesco 
Ariis, which was not a clue at all, it simply said "use recursion", 
while Jorge Maldonado explicitly said that he would use recursion...
