唔,首先这题给出了中序遍历和后序遍历要求我们求出, 一个叶子节点到根的数值总和最小,且这个叶子节点是最小的那个 这题的难点在于如何运用中序遍历和后序遍历还原整棵树, 这里有两个方法: 1. 递归构造原树.1. 运用链表构造一棵树. 我将要运用的是链表构造树. #include<bits/stdc++.h> using namespace std; struct Node{ int v; Node *left,*right; };//首先利用结构体构造树的节点 Node *root;//申请根节…
这道题目本身不难,给出后序遍历和中序遍历,求到节点最小路径的叶子,同样长度就输出权值小的叶子. Uva上不去了,没法測.基本上是依照ruka的代码来的.直接上代码 //Uva548 Tree #include<iostream> #include<algorithm> #include<string> #include<sstream> #include<cctype> using namespace std; const int maxv=10…
Tree You are to determine the value of the leaf node in a given binary tree that is the terminal node of a path of least value from the root of the binary tree to any leaf. The value of a path is the sum of values of nodes along that path.Input The i…
Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. 问题:给定一个二叉树,判断其是否平衡. 当二叉树中所有节点的左右子树高…

Given an array of numbers, verify whether it is the correct preorder traversal sequence of a binary search tree. You may assume each number in the sequence is unique. Follow up: Could you do it using only constant space complexity? 这道题让给了我们一个一维数组,让我们…
题目: Given preorder and inorder traversal of a tree, construct the binary tree. Note:You may assume that duplicates do not exist in the tree. 解题思路分析: 前序遍历首先遍历根节点,然后依次遍历左右子树 中序遍历首先遍历左子树,然后遍历根结点,最后遍历右子树 根据二者的特点,前序遍历的首节点就是根结点,然后在中序序列中找出该结点位置(index),则该结点之…
Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. Calling next() will return the next smallest number in the BST. Note: next() and hasNext() should run in average O(1) time and uses…
