https://www.luogu.org/problemnew/show/P1596 连通块水题... 大体思路是找到是水坑的坐标然后就开始不断递归,往八个方向搜,把连在一起的都标记一遍直到找不到为止 以下是本蒟蒻的代码 #include <bits/stdc++.h>//万能头 using namespace std; ][]; ]={,-,-,-,,,,,};//x方向 ]={,-,,,-,,-,,};//y方向 ; void dfs(int x,int y) { a[x][y]='.'…

\(problem\) 其实这题吧\(DFS\)好写一点(大雾 所以就不讲\(DFS\)了 em \(BFS\)的话 主要是 判重. 方向. 队列.(没了吧 至于位置 用两个队列?还是\(pair\)?还是结构体? \[\text{结构体大法好啊.emm}\] #ifdef Dubug #endif #include <bits/stdc++.h> using namespace std; typedef long long LL ; inline LL In() { LL res(0),f(…

可爱的题面君~~ 个人感觉这题还是很简单的,就是一个完全不加工的找联通块个数 个人解题思路是先读入,然后循环一遍,遇到水就dfs,并把这个w所在的联通块“删除”,并在答案上加一 最后输出答案 具体注释看程序::: #include<cmath> #include<cstdio> #include<iostream> #include<cstring> #include<algorithm> using namespace std; int n,m…
