刷题94. Binary Tree Inorder Traversal

一.题目说明题目94. Binary Tree Inorder Traversal,给一个二叉树,返回中序遍历序列.题目难度是Medium! 二.我的解答用递归遍历,学过数据结构的应该都可以实现. class Solution{ public: vector<int> inorderTraversal(TreeNode* root){ if(root != NULL){ if(root->left !=NULL)inorderTraversal(root->left); res…

LeetCode（94）Binary Tree Inorder Traversal

题目如下: Python代码: def inorderTraversal(self, root): res = [] self.helper(root, res) return res def helper(self, root, res): if root: self.helper(root.left, res) res.append(root.val) self.helper(root.right, res)…

[线索二叉树] [LeetCode] 不需要栈或者别的辅助空间，完成二叉树的中序遍历。题：Recover Binary Search Tree，Binary Tree Inorder Traversal

既上篇关于二叉搜索树的文章后,这篇文章介绍一种针对二叉树的新的中序遍历方式,它的特点是不需要递归或者使用栈,而是纯粹使用循环的方式,完成中序遍历. 线索二叉树介绍首先我们引入“线索二叉树”的概念: "A binary tree is threaded by making all right child pointers that would normally be null point to the inorder successor of the node, and all left chi…
