Morris Traversal方法遍历二叉树（非递归，不用栈，O(1)空间）

本文主要解决一个问题，如何实现二叉树的前中后序遍历，有两个要求：1.O(1)空间复杂度，即只能使用常数空间；2.二叉树的形状不能被破坏（中间过程允许改变其形状）。通常，实现二叉树的前序（preorder）、中序（inorder）、后序（postorder）遍历有两个常用的方法：一是递归(recursive)，二是使用栈实现的迭代版本(stack+iterative)。这两种方法都是O(n)的空间复

LeetCode---Binary Tree Level Order Traversal、Binary Tree Level Order Traversal II解题分析

题意描述：给定一棵二叉树，按层次顺序输出。比如给定序列：{3,9,20,#,#,15,7}，其对应的二叉树、从根到叶层次顺序输出、逆向层次输出依次如下二叉树的逻辑视图：按从根结点到叶结点层次顺序输出：从叶结点到根结点的层次顺序输出：解题思路：这就用到了二叉树的层次遍历，用队列依次存放每个的结点；在判断每层结束时这里用的是用一个临时链表一层时暂时存该层结点，当该链表为空时这一层遍历完毕，同时将其加入
