[LeetCode] Binary Tree Postorder Traversal 二叉树的后序遍历

Given a binary tree, return the postorder traversal of its nodes' values. For example: Given binary tree {1,#,2,3}, 1 \ 2 / 3 return&nb...

[LeetCode] Construct Binary Tree from Inorder and Postorder Traversal 由中序和后序遍历建立二叉树

Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 这道题要求从中序和后序...

LeetCode: 106_Construct Binary Tree from Inorder and Postorder Traversal | 根据中序和后序遍历构建二叉树 | Medium

要求:根据中序和后序遍历序列构建一棵二叉树 代码如下: 1 struct TreeNode { 2 int val; 3 TreeNode *left; 4 TreeNode *right; 5 TreeNode(int x): val(x),left(NULL), right(NULL) {} 6...

LeetCode:145_Binary Tree Postorder Traversal | 二叉树后序遍历 | Hard

题目:Binary Tree Postorder Traversal 二叉树的后序遍历,题目要求是采用非递归的方式,这个在上数据结构的课时已经很清楚了,二叉树的非递归遍历不管采用何种方式,都需要用到栈结构作为中转,代码很简单,见下: 1 struct TreeNode { 2 int val; 3 ...
