I would caution the OP against blindly soliciting for free
homework answers on the internet, most especially when the
request includes the deletion of files. Perhaps in this
forum the worst case scenario would be the return of a
scornful rebuke or a heavily obfuscated chunk of abysmal
code. However, in some of the darker, more devious corners
of the web, a naive solicitation such as this could end with
the student's file-system suddenly being relieved of the
burden of carrying around all those extra files. A most
unforgiving lesson in the power and conciseness of the
recursive algorithm.
