N皇后問題一、當n mod 6 != 2 且 n mod 6 != 3時,有一個解為: 2,4,6,8,...,n,1,3,5,7,...,n-1 (n為偶數) 2,4,6,8,...,n-1,1,3,5,7,...,n (n為奇數) (上面序列第i個數為ai,表示在第i行ai列放一個皇后;... 省略的序列中,相鄰兩數以2遞增。下同) 二、當n mod 6 == 2 或 n mod 6 == 3時, (當n為偶數,k=n/2;當n為奇數,k=(n-1)/2) k,k+
——A: POD類型:Plain Old Data ;非 POD 類型通常需要初始化,不論是調用預設的建構函式(編譯器提供的)還是自己寫的建構函式。——B:C++在聲明定義一個類的時候 ,virtual 函數佔用4個位元組(虛函數表);空的類是一個位元組,用於存放資料;——C:模板 枚舉的 傳神用法:template<int num>struct Fib{enum {result=Fib<num-1>::result+Fib<num-2>::result};
