463. Island Perimeterhttps://leetcode.com/problems/island-perimeter/就是逐一遍历所有的cell,用分离的cell总的的边数减去重叠的边的数目即可.在查找重叠的边的数目的时候有一点小技巧,就是沿着其中两个方向就好,这种题目都有类似的规律,就是可以沿着上三角或者下三角形的方向来做.一刷一次ac,但是还没开始注意codestyle的问题,需要再刷一遍. class Solution { public: int islandPerime…

  参考文档:CEPH官网集群操作文档   概述 Ceph存储集群是所有Ceph部署的基础. 基于RADOS,Ceph存储集群由两种类型的守护进程组成:Ceph OSD守护进程(OSD)将数据作为对象存储在存储节点上; Ceph Monitor(MON)维护集群映射的主副本. Ceph存储集群可能包含数千个存储节点. 最小系统将至少有一个Ceph Monitor和两个Ceph OSD守护进程用于数据复制.   Ceph文件系统,Ceph对象存储和Ceph块设备从Ceph存储集群读取数据并将数据写…
