1、BFS和DFS 深度优先搜索算法(DFS)和广度优先搜索算法(BFS)是一种用于遍历或搜索树或图的算法,在搜索遍历的过程中保证每个节点(顶点)访问一次且仅访问一次,按照节点(顶点)访问顺序的不同分为深度优先和广度优先。 1.1、深度优先搜索算法 深度优先搜索算法(Depth-First-Search,DFS)沿着树的深度遍历树的节点,尽可能...

LeetCode 两次踩坑后,我终于学会了 BFS 上周末的时候参加 LeetCode 周赛,碰到了一道题。感觉很有意思,而且收获也不小,记录一下。 题目链接如下: https://leetcode-cn.com/problems/map-of-highest-peak/ 题目描述: 给你一个大小为m x n的整数矩阵isWater,它代表了一个由陆地和水域单元格组成的地图。
The maze contains at least 2 empty spaces, and both the width and height of the maze won't exceed 100. Solution - DFS class Solution { public boolean hasPath(int[][] maze, int[] start, int[] destination) { int m = maze.length, n = maze[0].length; ...
