Feagty and Rado must be banned I think. Because their E,D and B solutions are same. I looked their codes and understood that. That's enough. I'm fed up that someones cheats on exams. If you want , you can look their codes. Links are here :
Feagty's 'B' solution : 3457229 Rado's 'B' solution : 3462615
Feagty's 'D' solution : 3463129 Rado's 'D' solution : 3458125
Feagty's 'E' solution : 3463479 Rado's 'E' solution : 3461438
Please look at the submission's time and numbers. Feagty solved 'B' earlier than Rado and Rado solved 'D' and 'E', earlier than Feagty. And a little detail : Rado's solutions's('D' and 'E') language is Java 6. But Feagty's solution's('B') language is GNU C++ both of them.
Please look at their codes and ban them !!!
