线性表顺序存储结构和链式存储结构

顺序存储结构就是用一组地址连续的存储单元依次存储该线性表中的各个元素。由于表中各个元素具有相同的属性,所以占用的存储空间相同。
线性表按链式存储时,每个数据元素 (结点)的存储包括数据区和指针区两个部分。数据区存放结点本身的数据,指针区存放其后继元素的地址只要知道该线性表的起始地址表中的各个元素就可通过其间的链接关系逐步找到

优缺点
顺序存储需要开辟一个定长的空间,读写速度快,缺点不可扩充容量(如果要扩充需要开辟一个新的足够大的空间把原来的数据重写进去)

链式存储无需担心容量问题,读写速度相对慢些,由于要存储下一个数据的地址所以需要的存储空间比顺序存储大。

CKA Simulator Kubernetes 1.22

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
