Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree [1,null,2,3], return [1,3,2]. Note: Recursive solution is trivial, could you do it iteratively? 解析 嘻嘻,最近因为马

今天在切leetcode的时候看到一个Morris算法,用来中序遍历二叉树,非递归,O(1)空间。觉得很强大。记录一下。基本思想是利用了Threaded Binary Tree。步骤如下:current节点设置为root。如果current不为空,到2,否则返回;如果current没有左子树,输出c
inorder的用法总结 在数据结构开发工作中，处理二叉树（BinaryTree）遍历是高频操作。其中左子树-根节点-右子树的访问顺序，是解析表达式树或构建有序输出的核心手段。去年为某物流系统优化路径计算模块时，我们通过调整该遍历方式，将仓库节点排序效率提升40%，这是通过递归算法实现的典型应用。递归实现需要注意栈深度限制...
