N Queens Problem is a famous puzzle in which n-queens are to be placed on a nxn chess board such that no two queens are in the same row, column or diagonal. In this tutorial I am sharing the C program to find s
b)若当前行不是最后一行,当前行设为下一行, 当前列设为当前行的第一个待测位置; c)若当前行是最后一行,当前列不是最后一列,当前列设为下一列; d)若当前行是最后一行,当前列是最后一列,回溯,即清空当前行及以下各行的棋盘,然后,当前行设为上一行,当前列设为当前行的下一个待测位置。 e)以上返回到第2...
