DescriptionA square is a 4-sided polygon whose sides have equal length and adjacent sides form 90-degree angles. It is also a polygon such that rotating about its centre by 90 degrees gives the same

DescriptionYou may have heard that no two snowflakes are alike. Your task is to write a program to determine whether this is really true. Your program will read information about a collection of s

数据结构实验之查找一：二叉排序树题目描述对应给定的一个序列可以唯一确定一棵二叉排序树。然而，一棵给定的二叉排序树却可以由多种不同的序列得到。例如分别按照序列{3,1,4}和{3,4,1}插入初始为空的二叉排序树，都得到一样的结果。你的任务书对于输入的各种序列，判断它们是否能生成一样的二叉排序树。输入输入包含若干组测试数据。每组数据的第1行给出两个正整数N (n

数据结构实验之查找七：线性之哈希表Time Limit: 1000ms   Memory limit: 65536K  有疑问？点这里^_^题目描述根据给定的一系列整数关键字和素数p,用除留余数法定义hash函数H(Key)=Key%p,将关键字映射到长度为p的哈希表中，用线性探测法解决冲突。重复关键字放在hash表中的同一位置。输入连续输入多组数据

数据结构实验之查找三：树的种类统计题目描述随着卫星成像技术的应用，自然资源研究机构可以识别每一个棵树的种类。请编写程序帮助研究人员统计每种树的数量，计算每种树占总数的百分比。输入输入一组测试数据。数据的第1行给出一个正整数N (n 输出按字典序输出各种树的种类名称和它占的百分比，中间以空格间隔，小数点后保留两位小数。示例输入30As

DescriptionYou are given a bunch of wooden sticks. Each endpoint of each stick is colored with some color. Is it possible to align the sticks in a straight line such that the colors of the endpoints

DescriptionFarmer John's N cows (1 ≤ N ≤ 100,000) share many similarities. In fact, FJ has been able to narrow down the list of features shared by his cows to a list of onlyK different features
