I'm pretty sure all those questions are already answered and i've seen you posting links to these questions a lot
anyways i'll answer them
It is the second time I have posted links to these questions. And the questions where answered by that guest that always gets it wrong (not to be rude but thats the truth) I even tested the guests answers and my website showed them as wrong.
Which website?
I am guessing AoPS... because that's where many questions come from.
