traversal of binary tree 英文traversal of binary tree 中文【计】 二叉树遍历
If a binary tree is traversedin-order, the output will produce sorted key values in an ascending order. We start fromA, and following in-order traversal, we move to its left subtreeB.Bis also traversed in-order. The process goes on until all the nodes are visited. The output of in-or...
The order our nodes have been explored in is A, B, C, D, E, F, G, H, and I. The breadth first traversal approach is a bit like exploring a tree in a very organized and methodical way. This is quite a bit different than our next traversal approach... Depth-First Traversal The ...

We shall perform Depth First Traversal on the above Binary tree; Depth First consists of PreOrder, InOrder, and PostOrder; we shall see PostOrder traversing here. PostOrder( Left Subtree, Right Subtree, Root node ): D E B C A The steps followed to get PostOrder is simple, Visit the left...
Given a binary tree, return theinordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 return[1,3,2]. Note:Recursive solution is trivial, could you do it iteratively? 递归的方法这里就不多说,下面主要提供两个非递归算法:1、使用栈的非递归中序遍历;...
