网上的题解大都模糊,我可能写的也比较模糊吧,讲究看看. 大致题意: 原图没有一个割点时,特殊考虑,至少ans1=2个通风井,方案数n*(n-1)/2; 原图上有多个割点时,每个(由割点限制成几部分的)联通块个数即为ans1:需要dfs进行vis标记和iscut区分,不重不漏: ans2,建设时避开在割点上建设通风井(通风井数量可最小化,以免通风井损毁后还需再建一个以备万一):求解时:当一个颜色块有两个割点时,摧毁一个蚂蚁们总可以通过另一个割点紧急转移:当一个颜色块有仅一个割点时,摧毁割点后就必须…

NFS(Network File System/网络文件系统): 设置Linux系统之间的文件共享(Linux与Windows中间文件共享采用SAMBA服务): NFS只是一种文件系统,本身没有传输功能,是基于RPC协议实现的,才能达到两个Linux系统之间的文件目录共享: NFS为C/S架构: NFS 的基本原则是“容许不同的客户端及服务端通过一组RPC分享相同的文件系统”,它是独立于操作系统,容许不同硬件及操作系统的系统共同进行文件的分享. NFS在文件传送或信息传送过程中依赖于RPC协议.…
