遍历
遍历集合，按照指定的集合进行拼接的两种方式：
StringBuilder

如30%的甲，70%的乙：
创建一个新的集合：赋30%的”1”，赋70%的”2”
对所创建的集合元素进行随机取值：Random r = new Random();
对随机取得的值进行条件判断，取到的值就有概率

注意：
线性表可以是空表，树可以是空树，但图不可以是空，即v一定是非空集
无向图、有向图
简单图、多重图
简单图
多重图
顶点的度、入度、出度
无向图：顶点v的度是指依附于改顶点的边的条数，极左TD(v)
有向图：
入读是以顶点v为终点的有向边的数目，记为ID(v)
出度是以顶点v为起点的有向边的数目，记为OD(v)
顶点的度等于入度和出度之和，TD(v)=ID(v)+OD(v)
顶点-顶点的关系描述
路径：顶点v1到顶点v2之间的一条路径
回路：第一个顶点和最后一个顶点相同的路径称为回路或环
简单路径：在路径序列中，顶点不重复出现的路径称为简单路径。
简单回路:除第一个顶点和最后一个顶点外，其余顶点不重复出现的回路称为简单回路。
路径长度:路径上边的数目
点到点的距离:从顶点u出发到顶点v的最短路径若存在，则此路径的长度称为从u到v的距离。若从u到v根本不存在路径，则记该距离为无穷
无向图中，若从顶点v到顶点w有路径存在，则称v和w是连通的
有向图中，若从顶点v到顶点w和从顶点w到顶点v之间都有路径，则称这两个顶点是强连通的

红黑树
红黑树是一种自平衡的二叉查找树，是计算机科学中用到的一种数据结构。
1972年出现，当时被称之为平衡二叉B树。后来，1978年被修改为如今的”红黑树”。
它是一种特殊的二叉查找树，红黑树的每一个节点上都有存储位表示节点的颜色，
每一个节点可以是红或者黑;红黑树不是高度平衡的，它的平衡是通过”红黑规则”进行实现的
红黑规则
每一个节点或是红色的，或者是黑色的
根节点必须是黑色
如果一个节点没有子节点或者父节点，则该节点相应的指针属性值为Nil，这些Nil视为叶节点，每个叶节点(Nil)是黑色的
如果某一个节点是红色，那么它的子节点必须是黑色(不能出现两个红色节点相连的情况)
对每一个节点，从该节点到其所有后代叶节点的简单路径上，均包含相同数目的黑色节点;
红黑树添加节点的规则：
添加节点默认是红色(效率高)

我为什么要搭建个人博客？
记录美好生活；
提升自己的技术水平；
空闲时间娱乐；
本博客由Github+Hexo搭建，下面我来介绍我做这个博客的全过程：
注册GitHub
首先进入GitHub官网
点击Sign up
输入你要注册的邮箱、密码
Create account
依次按照github的提示来做，之后就省略，不难。
Git安装步骤
进入Git官网,想、点击Downloads
选择自己的系统
选择自己的适合的版本
( 国内下载的速度慢，有时候还会下载失败，我这里提供Git-2.40.1-64-bit的安装包 )
下载完成打开
鼠标左击出现这种情况就可以了
打开Git Bash，输入git出现这种情况就可以了
绑定GitHub并提交文件
打开Git bash 输入ssh，查看本机是否安装SSH
