技巧:遍历8个方向 ; dr <= ; dr++) ; dc <= ; dc++) || dc != ) dfs(r+dr, c+dc, id); 我的解法: #include<cstdio> #include<cstring> #include<iostream> #include<string> #include<algorithm> using namespace std; ; char buf[N][N]; int m,…

小白书上经典DFS题目. 1. 递归实现 // from: https://www.cnblogs.com/huaszjh/p/4686092.html #include <stdio.h> #include <string.h> #define maxn 105 unsigned char data[maxn][maxn]; int m, n, vis[maxn][maxn]; void dfs(int x, int y, int ans) { if (x < 0 || x…

解题思路:好久没写搜索了,练练手,陶冶情操.不多说,直接贴代码: #include<cstdio> #include<cstring> #include<algorithm> using namespace std; ; ][] = {-, -, -, , -, , , -, , , , -, , , , }; char gg[maxn][maxn]; int m, n; void DFS(int x, int y, int id) { || x > m || y…

[本博文非博主原创,均摘自:刘汝佳<算法竞赛入门经典>(第2版) 6.4 图] [程序代码根据书中思路,非独立实现] 例题6-12 油田(Oil Deposits,UVa572) 输入一个m行n列的字符矩阵,统计字符“@”组成多少个八连块.如果两个字符“@”所在的格子相邻(横.纵或者对角线方向),就说它们属于一个八连块.例如,下图中有两个八连块. 一.分析 1.1 整体思路 图也有DFS和BFS遍历.由于DFS更容易编写,一般用DFS查找连通块:从每个"@"格子出发,递归遍…
