07-图5 Saving James Bond - Hard Version   (30分) This time let us consider the situation in the movie "Live and Let Die" in which James Bond, the world's most famous spy, was captured by a group of drug dealers. He was sent to a small piece of lan

7-12 社交网络图中结点的“重要性”计算(30 分) 在社交网络中,个人或单位(结点)之间通过某些关系(边)联系起来.他们受到这些关系的影响,这种影响可以理解为网络中相互连接的结点之间蔓延的一种相互作用,可以增强也可以减弱.而结点根据其所处的位置不同,其在网络中体现的重要性也不尽相同. “紧密度中心性”是用来衡量一个结点到达其它结点的“快慢”的指标,即一个有较高中心性的结点比有较低中心性的结点能够更快地(平均意义下)到达网络中的其它结点,因而在该网络的传播过程中有更重要的价值.在有N个结点的网

L3-015 球队“食物链” (30 分)   某国的足球联赛中有N支参赛球队,编号从1至N.联赛采用主客场双循环赛制,参赛球队两两之间在双方主场各赛一场. 联赛战罢,结果已经尘埃落定.此时,联赛主席突发奇想,希望从中找出一条包含所有球队的“食物链”,来说明联赛的精彩程度.“食物链”为一个1至N的排列{ T​1​​ T​2​​ ⋯ T​N​​ },满足:球队T​1​​战胜过球队T​2​​,球队T​2​​战胜过球队T​3​​,⋯,球队T​(N−1)​​战胜过球队T​N​​,球队T​N​​战胜过球队

Suppose that all the keys in a binary tree are distinct positive integers. A unique binary tree can be determined by a given pair of postorder and inorder traversal sequences. And it is a simple standard routine to print the numbers in level-order. H

title: 04-树6 Complete Binary Search Tree(30 分) date: 2017-11-12 14:20:46 tags: - 完全二叉树 - 二叉搜索树 categories: 数据结构 题目链接 题目大意 给出n个节点,构造一棵完全二叉搜索树. 最后按层次遍历输出这棵树. 分析 搜索二叉树的中序遍历是按照由小到大的顺序遍历的. 而完全二叉树,知道树的结点后就可以唯一确定树的结构,因此知道树的结点数后,中序遍历并将结点由小到大给树赋值,就可以构建出树. AC代

7-2 二叉搜索树的结构(30 分) 二叉搜索树或者是一棵空树,或者是具有下列性质的二叉树: 若它的左子树不空,则左子树上所有结点的值均小于它的根结点的值:若它的右子树不空,则右子树上所有结点的值均大于它的根结点的值:它的左.右子树也分别为二叉搜索树.(摘自百度百科) 给定一系列互不相等的整数,将它们顺次插入一棵初始为空的二叉搜索树,然后对结果树的结构进行描述.你需要能判断给定的描述是否正确.例如将{ 2 4 1 3 0 }插入后,得到一棵二叉搜索树,则陈述句如“2是树的根”.“1和4是兄弟结点
