任务：实现Dijkstra算法 工程名：Project_ShortestPath 要求：实现Dijkstra算法，算法主体写在CGraph类中；要求是从command窗口中输入源节点编号，并在command窗口中输出从源节点到所有目的节点的最短路长及最短路。注：要输出整条路径，而不仅仅是前一跳，也不允许逆序输出。 (Task: Dijkstra' s algorithm to achieve the project name: Project_ShortestPath requirements: achieve Dijkstra algorithm, the algorithm written in the body CGraph class requires input from the command window, the source node number, and in the command window, all of the output from the source node to the destination node shortest long and the shortest. Note: To export the entire path, not just before the jump, do not allow reverse output.)

根据队列搜索算法的基本思想，现设计了一个简单的结构体数组如下定义代码所示。此结构体数组具备控制结点搜索和存储结点信息和路径的功能，可以较好的实现TDN的最小时间路径搜索。(Search algorithm based on the basic idea of ​ ​ the queue is now designed a simple structure array as defined code. This structure array with the control node and storage node information search and path functions, you can achieve better TDN minimum time path search.)

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)

用不多于四种颜色为地图染色，使相邻的行政区不重色，是计算机科学中著名的“四染色”的典型应用，应用这个思想，是以回溯的算法对一幅给定的地图染色。是对数据结构中栈的应用。(With no more than four colors map staining the adjacent borough is not heavy color, typical applications of computer science "stain" the application of this idea, a backtracking algorithm on a given mapstaining. The application of the stack data structure.)
