I did say it was a trivial implementation, not an efficient one. :-)
I just wanted to illustrate the fact that the basic problem is trivial, 
and writing a solution can be done in no time, so what was the problem? 
Was someone looking for an efficient solution, a particularly clever 
one, or what was the point. And it appeared they just wanted a 
solution... :-)
