[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…
