叫 Morris Traversal,在介绍这种方法之前,先来引入一种新型树,叫Threaded binary tree,这个还不太好翻译,第一眼看上去以为是叫线程二叉树,但是感觉好像又跟线程没啥关系,后来看到网上有人翻译为螺纹二叉树,但博主认为这翻译也不太敢直视,很容易让人联想到为计划生育做出突出贡献的某世界...

Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. For example, given preorder = [3,9,20,15,7] inorder = [9,3,15,20,7] Return the following binary tre...

[leetcode] 94. Binary Tree Inorder Traversal Description Given a binary tree, return the inorder traversal of its nodes’ values. Example: Input: [1,null,2,3] 1 \ 2 / 3Output: [1,3,2] Follow up: Recursive solution is trivial, could you do it iteratively?
题目: Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 根据前序遍历和中序遍历结果构造二叉树。 思路分析: 分析二叉树前序遍历和中序遍历的结果我们发现: 二叉树前序遍历的第一个节点是根节点。 在中序遍历...
