先复习一下BST,给定一个节点,其左子树的所有节点都小于该节点,右子树的所有节点都大于该节点;preorder序列是指在遍历该BST的时候,先记录根节点,再遍历左子树,然后遍历右子树;所以一个preorder序列有这样一个特点,左子树的序列必定都在右子树的序列之前;并且左子树的序列必定都小于根节点,右子树的序列都大于根节点;...

Here is the complete example for the binary search tree traversal (In order, Preorder and Postorder) in Java. package com.javadevjournal.datastructure.tree.bst; public class BinarySearchTree { private Node root; /** * In order BST traversal allows to traverse tree in the sorted order. * T...
Pre: node 先, Inorder: node in, Postorder: node 最后 Recursive method 实际上代码是一样, 就是把ans.append(root.val) 放在如上表先, 中, 后就是pre, in, post order了. 1) PreOrder traversal ans =[]defpreOrder(self, root):ifnotroot:returnans.append(root.val)preOrder(root.left) ...
Find postorder traversal of BST from preorder traversal in C - In this problem we are given an array preOrder[] that represents the preorder traversal of the binary search tree. Our task is to Find postorder traversal of BST from preorder traversal.Let

postorder: we need to make sure all the children nodes for the current node has been visited before we visit current node, and the left subtree is visited before right subtree. preorder: classSolution{voidpushLeft(TreeNode*root,stack<TreeNode*>&nodes,vector<int>&res){// this function here...
