This post is intended to my students of course Design Patterns at PAF-KIET.
The paper of 2nd One Hour has been published at http://goo.gl/ZzQAV .
As Google Doc didn't upload the diagrams in word document therefore I uploaded the PDF file of this paper as well. You can access PDF file at http://goo.gl/GJCGi
Update: You need to submit your solution via email by 15th November 2011 till 11:59pm. You also need to appear in One-Hour paper scheduled by department.
Best of Luck!
Possible patterns: Abstract Factory, Factory Method, Builder, Strategy, Facade
