I signed up for a programming contest with my colleagues and guess what, we won! You guys must be great programmers. We had a good idea and we implemented it.  We were up against some tough competition. What did you win? We get a cash prize of ten thousand dollars.  The organizer is also donating a thousand dollars to our favorite charity. Everyone wins.
