题意:给出一个农田的图,n行m列,再给出k个被淹没的坐标( i , j ).求出其中相连的被淹没的农田的最大范围. 思路:dfs算法 代码: #include<iostream> #include<stdio.h> using namespace std; int t[150][150]; int visit[150][150]; int n,m,k; int dfs(int i,int j){ if(i<1||j<1||i>n||j>m||t[i][j]=…

poj 1523Tarjan算法的含义——求取割点可以分出的连通分量的个数 题目大意:如题目所示 给你一些关系图——连通图,想要问你有没有个节点,损坏后,可以生成几个互相独立的网络(也就是连通分量),所以我们利用tarjan算法,求取一个联通分量的点,记录次数,因为访问几次,就代表这个点的不同方向上的联通分量的个数,记录下来,最后输出即可 至于根节点的选取,选谁都没什么问题的,我默认选的节点1 嗯,没什么了,tarjan算法到这算是入门啦 #include <iostream> #includ…
