static int Square (int x){return x*x;}
static int Cube (int x){return x*x*x;}
static int Quartic (int x){return Square(Square(x));}
static int Quintic (int x){return Cube(Square(x));}
static double Max(double x,double y){return x>y?x:y}

Answer 3

这种问题当然要去问老师了！
你问外行人怎么可能知道答案！

Answer 4

我以前学(C#)也遇到很多问题，问也问不出个所以然来，最好还是自己多看看书吧。

Answer 5

这题都难? 我晕... 刚学C#就做这些.

Answer 6

太难了
