▶ 扫雷的扩展判定.已知棋盘上所有点的情况(雷区 'M',已翻开空白区 'B',未翻开空白区 'E',数字区 '1' ~ '8'),现在给定一个点击位置(一定在空白区域),若命中雷区则将被命中的 M 改为 X,若命中空白区则将点击位置扩展为带有数字边界的安全区. ● 自己的解法,28 ms,深度优先遍历.改善了边界判定的方法,以后写类似的矩阵函数的时候可以借鉴.实际上可以在 extend 开头判定 click 是否在棋盘范围内,以后就可以强行 8 个方向搜索(见后面大佬的代码) class So…

BFS基础 广度优先搜索(Breadth First Search)用于按离始节点距离.由近到远渐次访问图的节点,可视化BFS 通常使用队列(queue)结构模拟BFS过程,关于queue见:算法与数据结构基础 - 队列(Queue) 最直观的BFS应用是图和树的遍历,其中图常用邻接表或矩阵表示,例如 LeetCode题目 690. Employee Importance: // LeetCode 690. Employee Importance/* class Employee { publi…

DFS基础 深度优先搜索(Depth First Search)是一种搜索思路,相比广度优先搜索(BFS),DFS对每一个分枝路径深入到不能再深入为止,其应用于树/图的遍历.嵌套关系处理.回溯等,可以用递归.堆栈(stack)实现DFS过程. 关于广度优先搜索(BFS)详见:算法与数据结构基础 - 广度优先搜索(BFS) 关于递归(Recursion)详见:算法与数据结构基础 - 递归(Recursion) 树的遍历 DFS常用于二叉树的遍历,关于二叉树详见: 算法与数据结构基础 - 二叉查找树…
