用c/c++写的二叉排序树的插入与删除，有兴趣的朋友可以看一下(Insertions and deletions using c/c++ to write binary sort tree)

图的遍历问题 数据结构 C C++ 源码 课程设计 严蔚敏版的书(yrteryryer)

实现排序操作SortDemoSortDemo.rar,很不错的vc源码，希望对大家有所帮助。(To achieve the sorting operation SortDemo SortDemo.rar, very good vc source, we want to help.)

USACO中的American heritage，用C++编写，运用了树的遍历知识(the American heritage of USACO, with C++ prepared, using a tree traversal knowledge)

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)

说明：  数据结构：Huffman编码。哈夫曼编码是哈夫曼树的一个应用。哈夫曼编码应用广泛，如JPEG中就应用了哈夫曼编码。 哈夫曼树又称最优二叉树，是一种带权路径长度最短的二叉树。(Data structure: Huffman coding. Huffman coding is an application of the Huffman tree. Huffman coding is widely used, such as JPEG in the application of the Huffman coding. Huffman tree, also known as the best binary tree is a weighted shortest path length binary tree.)

说明：  用数据结构的遍历，对于小毛驴过河解决实际问题。(Traversing the data structure used for the small donkey across the river to solve practical problems.)

主要用栈和树求解骑士问题，用C++语言编写的(The main stack and tree Cavalier Problem Solving with C++ languages)

数据结构课程设计，在VC环境下完成，利用哈夫曼树原理，主要功能是实现字符的压缩和解压缩，设计脉络清晰，易懂(Data structure course design, completed in the VC environment, using Huffman tree principle, the main function is to achieve the character of the compression and decompression, design, clear structure, easy to understand)

说明：  斐波那契 式子计算，属于算法类的 用于VC6.0++(Fibonacci calculation formulas, algorithms are used to VC6.0++ class)
