链接 : Here! 思路 : 搜索判断连通块个数, 所以 $DFS$ 或则 $BFS$ 都行喽...., 首先记录一下整个地图中所有$Oil$的个数, 然后遍历整个地图, 从油田开始搜索它所能连通多少块其他油田, 只需要把它所连通的油田个数减去, 就ok了 /************************************************************************* > File Name: E.cpp > Author: > Mail: >…

题目大意:给你一个m*n的矩阵,里面有两种符号,一种是 @ 表示这个位置有油田,另一种是 * 表示这个位置没有油田,现在规定相邻的任意块油田只算一块油田,这里的相邻包括上下左右以及斜的的四个方向相邻的位置.要你求出一共有多少块油田. 解题报告:用dfs,我的做法是首先在输入的时候将每个有油田的位置标记为1,否则标记为0,然后枚举每一个点,如果这个点有油田,则以这个点为起点,像周围的八个方向搜索,搜到了相邻的点就标记为2,当然这里也可以标记为0,只要是将已经搜过的点标记掉就是了,当dfs退出到ma…
