[leetcode]_Binary Tree Inorder Traversal

题目:二叉树的中序遍历. 思路:用递归来写中序遍历非常简单.但是题目直接挑衅说,----->"Recursive solution is trivial".好吧.谁怕谁小狗. 递归代码: List<Integer> inOrder = new ArrayList<Integer>(); public List<Integer> inorderTraversal(TreeNode root) { inOrderT(root); return in…

leetcode第一刷_Binary Tree Inorder Traversal

递归实现当然太简单,也用不着为了ac走这样的捷径吧..非递归实现还挺有意思的. 树的非递归遍历一定要借助栈,相当于把原来编译器做的事情显式的写出来.对于中序遍历,先要訪问最左下的节点,一定是进入循环后,不断的往左下走,走到不能走为止,这时候,能够从栈中弹出訪问的节点,相当于"左根右"过程的"根",然后应该怎么做呢?想一下中序遍历完根节点之后应该干嘛,对,是走到右子树中继续反复这个过程,可是有一点,假设这个节点不包括右子树怎么办?这样的情况下,下一个应该訪问的节点应该…

[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…
