Tree security label component: a tree is a collection of elements representing a complex hierarchy having multiple nodes and branches.
树安全标签组件：树是一个元素集合，用于表示有多个节点和分支的复杂层次关系。
Think about a company like Amazon and the common "Customers who purchased X also purchased y" feature. If Amazon were to create a classification tree, how many branches and nodes could it have?
举个例子，亚马逊这样的公司常常使用“购买了X的顾客还购买了Y ”特性，如果亚马逊拟创建一个分类树，那么它将需要多少分支和节点？
As each node receives updates, it branches off and updates additional nodes.
当每个节点收到更新信息时，它都进行分叉并且更新其他节点。
