流程是先反转数组,然后取出顶级数组入栈,开始while循环,先出栈一个查找其下有没有子节点,如果有子节点,则将此子节点也入栈,下次while循环就会查子节点的,依次类推: functiongetTreeOptions2($list,$pid= 0) {$tree=[];if(!empty($list)) {//先将数组反转,因为后期出栈时会优先出最上面的$list=array_rev...
Because the adjacency list model is still more common, you can expect to have to convert it into a nested sets model. There are a few ways to do this. 4.10.1 Stack Algorithm To convert an adjacency list model to a nested sets model, use this bit of SQL/PSM code. It is a simple ...
Adjacency Matrix of Graph Create a directed graph using an edge list, and then find the equivalent adjacency matrix representation of the graph. The adjacency matrix is returned as a sparse matrix. s = [1 1 1 2 2 3]; t = [2 3 4 5 6 7]; G = digraph(s,t) ...
简介:图的邻接表实现 Adjacency List of the Graph eryar@163.com 一、图的邻接表 邻接表(Adjacency List)是图的一种链式存储结构。在邻接表中,对图中每个顶点建立一个单链表,第i个单链表中的结点表示依附于顶点Vi的边,对有向图是以顶点Vi为尾的弧。
