这是一个堆排序的算法源程序，算法被单独写成一个函数，希望对大家有用(This is a heap sort algorithm source code, algorithms are written as a separate function, we hope to be useful)

好用的平衡二叉树类库，C++类库编写， 好用的平衡二叉树类库，C++类库编写(AVL tree implementation for C++)

快速排序，用数组的存储结构，实现数的排序。共有八组随机数据，还能够计算出每组数据的处理时间，最终得到平均时间。(Quicksort array storage structure, to achieve the sort of number. A total of eight sets of random data, but also be able to calculate the processing time of each data, and eventually obtain the average time.)

常用的算法经典代码，包括快速排序，冒泡排序等各种排序方法，还有二叉树的前序、中序和后序遍历等(The classic algorithm code, including quick sort and bubble sort sorting methods, as well as the preamble of the binary tree, inorder and postorder traversal, etc.)

图的遍历的实现，文字界面，包含深度遍历和广度遍历两种情况~~(Graph traversal implementation, the text interface, including the depth and breadth traversal traverse both cases ~ ~)

这个是C++编译的单链表，其中包括多种链表操作，是很好的学习资料。(This is a C++ compiler single linked list, which includes a variety of linked list operations, is a good learning materials.)

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)
