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={...

105. Construct Binary Tree from Preorder and Inorder Traversal,这道题用指针,分治思想,相信看代码就能很容易弄懂了这里有一个问题未解决(希望有人可以回答一下:buildTree函数如果不加if语句在input为两个空vector对象的时候报错,搞不清楚为什么,因为我的build函
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 ...
144. Binary Tree Preorder Traversal 这个系列有preorder inorder postorder三题,考点都不是递归,而是迭代。迭代挺难想的,尤其是外面的while循环。这题的迭代写法我模仿inorder写出来了,一步步在纸上模拟入栈出栈就好了。 RECURSION: ITERATION: 看了下discussion,很多跟我写的都不一样,说明迭代写法确实比递归...
