Quals 2010 #1

I noticed that there are some same solutions on competitions ...
Maybe with little changes, like different name for variables, or changed for loop in while loop, or something like that ... But it is same ...
And some problems were discussed on chat while the competition lasted ...

I don't accuse anyone, but try to be fair, don't cheat ...

And what about that topic? Will there be any changes or just comments in this regard?
I dont want to add scores to myself, I think you have to recheck contestants' solutions fairly.
