江苏大学数据结构研究生试题2009Jiangsu University graduate examination papers(Jiangsu University graduate examination papers)

组合数学全排列,包含有六种全排列的方法，字典序法(math of permutations)

c语言完成的数据结构几个小算法游戏包括迷宫求解等(C language of complete data structure several small algorithm game includes maze solution, etc )

数据结构基础内容，两栈共享空间，参考《大话数据结构》(Structural basis of data content, two stacks shared space, refer to Westward data structure )

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)

输入迷宫行列数，1代表墙0代表路，之后系统生成路径(Enter the maze ranks number 1 represents 0 for Wall Road, after the system-generated path)

说明：  ACM及各类基本算法模板，包括数据结构，计算几何，字符串，图论，数学，高精度等许多常用模板(ACM basic algorithm and various templates, including data structures, computational geometry, string, graph theory, mathematics, high-precision, and many other commonly used templates)

c++实现的静态链表 可以从屏幕输入来构建静态链表 数据结构重要的部分(c++ implemented statically linked list can be input from the screen to the important part to build a static linked list data structure)

c++用栈来实现迷宫求解（c语言数据结构）(c++ stack maze solving (c language data structure))

大学计算机专业教材《数据结构》中栈的实验、练习源码(University computer professional teaching materials" data structure" stack experiment, practice source code)
