order Description 给出一棵二叉树的中序遍历和每个节点的父节点,求这棵二叉树的先序和后 序遍历. Input 输入第一行为一个正整数 n 表示二叉树的节点数目, 节点编号从 1 到 n,其中 1 为根节点.第 2 行有 n 个数字, 第 i 个数字表示 i 的父亲节点.( 1 的父亲节点为 0, 表示无)第 3 行为中序遍历.30%的数据: n<=20:60%的数据: n<=1000:100%的数据: n<=10000: Output 输出 2 行, 第一行为先序遍历,第…

Given inorder and level-order traversals of a Binary Tree, construct the Binary Tree. Following is an example to illustrate the problem. BinaryTree Input: Two arrays that represent Inorder and level order traversals of a Binary Treein[]    = {4, 8, 1…

题目: Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example:Given binary tree {3,9,20,#,#,15,7}, 3 / \ 9 20 / \ 15 7 return its level order traversal as: [ [3], [9,20], [15,7]…
