题意: 计算从根到叶节点的累加值,看看是否等于指定值.是输出yes,否则no.注意叶节点判断条件是没有左右子节点. 思路: 建树过程中计算根到叶节点的sum. 注意: cin读取失败后要调用clear恢复,否则后面无法正常读取. 注意空树都要输出no 最初代码如下:   #include<cstdio> #include<cstring> #include<iostream> #include<string> #include<algorithm>…

POJ.3321 Apple Tree ( DFS序 线段树 单点更新 区间求和) 题意分析 卡卡屋前有一株苹果树,每年秋天,树上长了许多苹果.卡卡很喜欢苹果.树上有N个节点,卡卡给他们编号1到N,根的编号永远是1.每个节点上最多结一个苹果.卡卡想要了解某一个子树上一共结了多少苹果. 现在的问题是不断会有新的苹果长出来,卡卡也随时可能摘掉一个苹果吃掉.你能帮助卡卡吗? 前缀技能 边表存储树 DFS时间戳 线段树 首先利用边表将树存储下来,然后DFS打上时间戳.打上时间戳之后,我们就知道书上节点对…

Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. For example, given preorder = [3,9,20,15,7] inorder = [9,3,15,20,7] Return the following binary tree: 3 / \ 9 20…
