Binary Tree Inorder Traversal 题目链接 题目要求: Given a binary tree, return theinordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 return[1,3,2]. Note: Recursive solution is trivial, could you do it iteratively?

Given a binary tree, return the inorder traversal of its nodes' values. 主要思路: 1.递归 保持左根右的顺序即可 代码: definorderTraversal(self,root):""" :type root: TreeNode :rtype: List[int] """ifroot==None:return[]left=self.inorderTraversal(root.left)right=self.inorderTraversal(root...
In order to traverse the binary tree, the successor of the node v in the order traversal is (assuming that the successor of v exists):对二叉树进行中序遍历,节点v在中序遍历下的后继为(假设v的后继存在): A.The first visited node in its right subtree其右子树中第一个被访问的节点B.The ...
