Given a binary tree, return thepreordertraversal of its nodes' values. Example: Input: [1,null,2,3]1\2/3Output: [1,2,3] Follow up: Recursive solution is trivial, could you do it iteratively? 方法一:使用迭代(C++) 1vector<int> preorderTraversal(TreeNode*root) {2vector<int> res={...

leetcode之Construct Binary Tree from Inorder and Postorder Traversal 问题 问题描述: Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 啰嗦一句,可能学过数据结构的人看到题目就知道啥意思了,给的问题介绍和描述...

Given a binary tree, return thepreordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 1. 2. 3. 4. 5. return[1,2,3]. 解法一: 递归方法: 如果root不为空, 先访问根,递归左子树,递归右子树。
The program creates a binary tree for breadth-first traversal.But i'm trying to use Pre-Order, In-Order, Post-Order Traversal and actually i can't do that. The output of the program is not what i expected. I think i should change the preorder, inorder or postorder functions but i ...
