https://leetcode.com/problems/binary-tree-postorder-traversal/description/ Description Implement an iterative, post-order traversal of a given binary tree, return the list of keys of each node in the tree as it is post-order traversed. Examples 5 / \ 3 8 / \ \ 1 4 11 Post-order trave...
If I understand the exercise correctly, you would have to come up with formulas for how to calculate the label of the left and right child during each method of traversal, given the label of the current node and the depth. For example, during pre-order traversal, the lab...
Post-order traversal is useful in some types of tree operations: Tree deletion. In order to free up allocated memory of all nodes in a tree, the nodes must be deleted in the order where the current node can only be deleted when both of its left and right subtrees are deleted. Evaluatin...

下列关于二叉树遍历的说法正确的有: Which sentences of the followings are right about traversal of a binary tree: A、前序和中序遍历的顺序恰好一样的二叉树,只能是空二叉树或者独根二叉树这两种情况。Only the sequences of preorder and infix order of t
Morris Traversal (好处是,Pre-Order和In-Order代码只有很小的改动) Morris Pre-Order Traversal (LeetCode 144) (Medium) 1...If left child is null, print the current node data. Move to right child. ….Else, Make the right child of the inorder predecessor point to the current node. Two cas...
Similar to pre-order and in-order traversal, accessing the binary tree in the order of left child->right child->root node is called post-order traversal. The first visited node in the post-order traversal is与先序、中序遍历类似,以左子->右子->根节点的顺序来访问二叉树称为后序遍历。后序...
""" Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. For example, given inorder = [9,3,15,20,7] postorder = [9,15,7,20,3] Return the following binary tree: 3 / \ 9 20 / \ 15 7...
