https://oj.leetcode.com/problems/n-queens-ii/ Follow up for N-Queens problem. Now, instead outputting board configurations, return the total number of distinct solutions. ===Comments by Dabay=== 不知道和N Queen相比有没有简单很多的方法。我这里的解法思路和N Queen一样的。
所以Problem 51 的 Python 代码如下: def NQueens(queenList,line): # 递归函数 # 当行数等于皇后数量时,记录结果 if line == queenNum: temp = [] for i in range(queenNum): s = '' for j in range(queenNum): if [i,j] in queenList: ...
为了封装N-Queens问题,创建名为NQueensProblem的Python类。用所需的问题大小初始化该类,并提供以下公共方法: getViolationsCount(positions):计算给定解违反约束的次数 plotBoard(positions):根据给定的解在棋盘上绘制皇后 棋子图片如下所示: 棋子 # 导入必要库 import numpy as np import matplotlib as mpl from matp...
