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)

合并果子,压缩是一种有效的减小数据量的方法,目前已经被广泛应用于各种类型的信息系统之中。
一种压缩文本文件的方法如下:
1. 原始文本文件中的非字母的字符,直接拷贝到压缩文件中;
2. 原始文件中的词(全部由字母组成),如果是第一次出现,则将该词加入到一个词的列表中,并拷贝到压缩文件中;否则该词不拷贝到压缩文件中,而是将该词在词的列表中的位置拷贝到压缩文件中。
3. 词的列表的起始位置为 1 。 词的定义为文本中由大小写字母组成的最大序列。大写字母和小写字母认为是不同的字母,即 abc 和 Abc 是不同的词。词的例子如下: * x-ray 包括两个词 x 和 ray * mary s 包括两个词 mary 和 s * a c-Dec 包括三个词 a 和 c 和 Dec 编写一个程序,输入为一组字符串,输出为压缩后的文本。(Fruit combined compression is an effective method for reducing the amount of data, has been widely applied to various types of information into the system. A method of compressing a text file is as follows: 1 original text file non-alphabetic characters, copy directly to the compressed file 2 words in the original document (all composed of letters), if it is the first time, then. The word is added to a word list, and copied to the compressed file otherwise the term is not copied to the compressed file, but the position of the word in the list of words copied to the archive. 3 the starting position is a list of words. The maximum term is defined by a sequence of text consisting of uppercase and lowercase letters. Uppercase and lowercase letters are considered different letters, ie abc and Abc are different words. Examples of the word as follows:* x-ray consists of two words x and ray* mary' s, including two words mary and s* a c-Dec consists of three words a and c and Dec to write )
