Binary Tree Inorder Traversal--leetcode
原题链接:https://oj.leetcode.com/problems/binary-tree-inorder-traversal/ 题目大意:中序遍历二叉树 解题思路:中序遍历二叉树,中序遍历二叉树的左子树,访问根结点,中序遍历二叉树的右子树。非递归实现时,用一个栈模拟遍历过程即可。因为需要先遍历左子树,所以每个结点先入栈,出栈时访问。 vector inorderTraversal(...

[LeetCode]Construct Binary Tree from Inorder and Postorder Traversal
Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 基本思想和知道前序与中序的思想一样,中序的某一节点的左节点一定是该节点的左子树,而后序遍历的某一节点的左节点一定...
