一．问题描述
对2006年度全国80多个城市的每天空气质量状况进行查询、排序等操作。
空气质量状况对象包括城市代码、城市名称、首要污染物、污染指数、污染物级别、空气状况、年、月、日
二、实验要求
1． 普通查询：输入城市名称和城市代码，分别查询该城市每天、每周、每月、每季度和全年的空气质量状况
例子：查询太原市2006年第8周的空气质量状况
2．统计查询：
（1）输入城市名称和城市代码，分别查询该城市每周、每月、每季度和全年的空气质量为优、良、轻微污染、轻度污染、重污染的天数
例子：查询石家庄市2006年第2季度空气质量为轻微污染的总天数
（2）根据时间查询空气质量状况：输入周编号、月编号、季度编号或年编号，以及空气质量为优、良、轻微污染、轻度污染、重污染的天数，查找相应的城市名称
例子：查询2006年5月，空气被轻度污染3天以上的城市有哪些？
3．排序查询
（1）输入周编号、月编号、季度编号或年编号，查询城市空气质量的排行榜
例子：查询2006年第6周，全国空气平均质量最好的前20个城市为哪些？
三、数据文件
Data.txt(one. Problem Description of the air quality day in 2006 more than 80 cities nationwide query, sorting and other operations. Air Quality objects include city code, city name, the primary pollutant, pollution index, contaminant level, air condition, year, month, day two, experimental requirements 1. General Queries: Enter a city name and city codes, each query in the city daily, weekly, monthly, quarterly example air quality and full year: Queries air quality in Taiyuan first eight weeks of 2006 2. Statistical inquiry: (1) enter a city name and city codes, each query in the city weekly, monthly, quarterly and annual air quality as excellent, good, slight pollution, light pollution, heavy pollution days example: inquiry Shijiazhuang City in 2006 second quarter, the air quality is the total number of days a slight pollution (2) according to time of the query air quality conditions: enter the week number, month number, quarter number or in number, and the air quality is excellent, good, sli)

Hash-table
哈希表
数据结构课程设计
1.1问题描述
针对自己的班集体中的“人名”设计一个哈希表，使得平均查找长度不超过R，完成相应的建表和查表程序。
1.2基本要求
假设人名为中国姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。构造哈希函数，用链表法处理冲突。
1.3测试数据
读取熟悉的30个人的姓名作测试。(Hash table
Data Structure Course Design
1.1 Description of the problem
For their own class group of the "names" to design a hash table, making the average search length does not exceed R, the completion of construction of tables and look-up table corresponding procedures.
1.2 Basic requirements
Assuming the name of the person called Chinese pinyin form. To be filled into a hash table names a total of 30, taking the average search length of the upper limit of 2. Construct a hash function, treatment with a list of conflict.
1.3 Test Data
Read the familiar names of 30 individuals tested.)
