Given a binary tree, return theinordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 return[1,3,2]. Note:Recursive solution is trivial, could you do it iteratively? 题解: 中序遍历:递归左 处理当前 递归右。 画图的话就是,之前离散老师教的,从ro...
今天介绍的是LeetCode算法题中Easy级别的第135题(顺位题号是589)。给定一个n-ary树,返回其节点值的前序遍历。例如,给定一个3-ary树: 1 / | \ 3 2 4 / \ 5 6 其前序遍历结果为:[1,3,5,6,2,4]。 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...
Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf to root). For example: Given binary tree {3,9,20,#,#,15,7}, 3/\920/\157 return its bottom-up level order traversal as: (II) [[15,7],[...

In our previous post, we saw how to implement a binary search tree in Java and how to insert nodes in binary search tree.In this post, we will talk about the binary tree traversal. We will work on java code for traversing a binary tree in Java. 1. Binary Tree Traversal Binary tree ...
