Java Binary Trees Why isn't it working? --- //adds a new Node to the tree (in a way of a Binary Search tree): public void add(int data){ insert(this.root, data); } private void insert(Node node, int data){ if (node == null){ //stops the recursion, some node will have ...
Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees ofeverynode never differ by more than 1. 新定义一个函数,表示树的高度,如果是平衡树的话。不是平衡树则置高度为-1....
本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 64位系统,使用Java语言编写和测试。 02 第一种解法 合并两个二叉树,首先我们需要遍历这两个二叉树的所有节点,其次是选择遍历顺序,是前序、中序还是后序,而题目说了要从根节点开始,那么我们选择前序遍历。二叉树的常规操作有递归、迭代的方法,此处...

Many of the "programming puzzle of the day", or "dev job interview questions" relate to binary trees. This repo contains a binary tree implementation in a Go package, as well as code that solves puzzle-or-problem-of-the-day questions.I...
If it is impossible to construct such a tree, print “NO” (without quotes) in the first line. Otherwise, print “{YES}” in the first line. Then print n−1 integers p2,p3,…,pn in the second line, where pi is the parent of the vertex i. Note that the sequence of parents you...
