Binary Tree Inorder Traversal Given a binary tree, return the inorder traversal 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? confused what "{1,#,2,3}" means? > ...

Note:Recursive solution is trivial, could you do it iteratively? 递归的方法这里就不多说,下面主要提供两个非递归算法:1、使用栈的非递归中序遍历;2、不使用栈的非递归中序遍历(Morris Traversal算法) 算法1:只要注意到每次要先遍历当前节点最左节点 ...

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? 中序遍历二叉树,递归遍历当然很容易,题目还要求不用递归,下面给出两种方法: ...
Given a binary tree, return theinordertraversal of its nodes' values. Example: Input: [1,null,2,3] 1 \ 2 / 3 Output: [1,3,2] Follow up: Recursive solution is trivial, could you do it iteratively? 二叉树的中序遍历顺序为左-根-右,可以有递归和非递归来解,其中非递归解法又分为两种,...
