If you have a look at our UF CoC Section II-6 (http://ubuntuforums.org/index.php?page=policy)

While we are happy to serve as a resource for hints and for asking questions when you get stuck and need a little help, the Ubuntu Forums should not be thought of as a homework service. Please do not post your homework assignments expecting someone else to do it for you. Any such threads will be taken offline and warnings or infractions may be issued.

Sorry, but we must deny such questions, 1- because we'll be overloaded and 2- because we are not part of any learning program. People gather here mainly for support with the Ubuntu distribution. I have removed the thread.
