首先发明这个算法的人肯定是对那个什么Threaded Binary Tree烂熟于心啊;其次,对inorder遍历也是理解透彻啊。。。 再次,这人思维肯定特清晰。 Reference:http://www.geeksforgeeks.org/inorder-tree-traversal-without-recursion-and-without-stack/

TheBreadth First SearchTraversal (BFS) is also one of the most important tree traversal algorithm. It traverses the binary tree in level-by-level order. For example, the above BFS traversal will give [0, 0, 2, 1.5, 3]. The implementation of a BFS is usually based on queue: 1 2 3 ...

In a threaded binary tree we link up the leaf nodes to point to its inorder successor. The same idea is bought into Morris Traversal. Below is the algorithm for Morris traversal and then we have presented a pictorial representation to describe the tr...
我们使用了相同的BinaryTree和TreeNode类,在早期的基于树的问题(例如计算叶节点)中,它用于表示二叉树。二叉树是常规二叉树,TreeNode表示二叉树中的节点。 importjava.util.Stack; /* * Java Program to traverse a binary tree * using inorder traversal without recursion. ...
2.1. Inorder Binary Tree Traversal In the in-order binary tree traversal, we visit the left sub tree than current node and finally the right sub tree. Here is the high-level algorithm for BST in-order traversal. 1. Traverse the left sub-tree (keep visit the left sub tree until you re...
