由n2个方块排成n行n列的正方形称为“n元棋盘”。如果两个皇后位于n元棋盘上的同一行或同一列或同一对角线上，则称它们为互相攻击。要求输出使n无棋盘上的n个皇后互不攻击的所有布局。 具体要求如下； (1)n可由键盘输入。 (2)在输入n后，动态建立方法说明中所需要建立的数组空间；程序运行结束时释放该存储空间。 (3)分别用n＝4，5，6运行你的程序。-by n2-n squares formed n trip out of a square called "n chessboard." If the two Queen's n chessboard at the same line or in the same series or on the same diagonal, claimed they attack each other. Request output enable chessboard n-n the Queen's not attack each other all the layout. Specific requirements are as follows; (1) n input from the keyboard. (2) n input, dynamic methodology established by the needs of an array of space; Running at the end of the release of the storage space. (3), respectively, n = 4,5,6 run your procedures.
