Si tratta del Google Code Jam 2004, un contest per sviluppatori in Java, C++, C# o VB.NET.

Estratto dal sito del Google Code Jam 2004:
Google is looking for engineers with the programming skill to rewrite the world's information infrastructure. The Google Code Jam 2004 is one way we hope to find them. While we don't impose arbitrary deadlines on our engineers, we do put a premium on well-implemented code. And we appreciate the thought process required to create it. In fact, we appreciate clear thinking in all its forms, from puzzle solving to chess mastery (one of our interns was an International Grand Master).
