jquery zTree 查找所有的叶子节点 // 保存所有叶子节点 10 为初始化大小,并非数组上限 var arrayObj = new Array([10]); /* treeNode: 根节点 result: 用于保存叶子节点的数组 */ // 获取所有叶子节点 function getAllLeafNodes(treeNode, result) { if (treeNode.isParent) { var childrenNodes = treeNode.children; if (c…

Given a binary tree, find all leaves and then remove those leaves. Then repeat the previous steps until the tree is empty. Example: Given binary tree 1 / \ 2 3 / \ 4 5 Returns [4, 5, 3], [2], [1]. Explanation: 1. Remove the leaves [4, 5, 3] from the…

Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q…

Given a binary tree, find the length of the longest consecutive sequence path. The path refers to any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The longest consecutive path need to be from p…
