数据结构 八皇后问题解决方案一 很好的代码

const int max_board = 30;

class Queens {
public:
   Queens(int size);
   bool is_solved() const;
   void print() const;
   bool unguarded(int col) const;
   void insert(int col);
   void remove(int col);
   int  board_size; //   dimension of board = maximum number of queens
private:
   int  count;      //   current number of queens = first unoccupied row
   bool queen_square[max_board][max_board];
};
