使用非递归的方法遍历二叉树，可以直接运行。( Non-recursive binary tree traversal.)

键盘任意输入一组字母或数字生成无序数组，对数组按ASCII顺序进行排序（排序要求至少用两种排序算法），再从键盘输入一个值进行二分查找，返回查找成功或者失败的信息(Keyboard input and a group of letters, or any number of arrays, and generate disordered array sort order according to the ASCII at least two requirements (sort of), sorting algorithms from the keyboard input a value dichotomy, returns to find success or failure of the information)

选择型结构c语言编程 (Choose the type of structure of C language programming)

This is a C++ code. It finds out if the tree is a binary search tree (BST)or not, where the BST is one of data structures types.

迷宫问题，利用随机数自动生成迷宫，并自动进行探索。迷宫起点及终点由用户自己设定。(Maze problem, the use of random number automatically generated maze, and automatically explore. The starting point and end point of the maze is set by the user. 双语对照 )

实现对二叉树的操作：建树、遍历、求层高、叶子数和结点数等(binary tree)

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)

利用數據結構中的棧，實現19世紀著名數學家高斯提出的八皇后問題(Stack data structure, to achieve the eight queens problem of the 19th century, the famous mathematician Gauss)

约瑟夫环（约瑟夫问题）是一个数学的应用问题：已知n个人（以编号1，2，3...n分别表示）围坐在一张圆桌周围。从编号为k的人开始报数，数到m的那个人出列；他的下一个人又从1开始报数，数到m的那个人又出列；依此规律重复下去，直到圆桌周围的人全部出列。通常解决这类问题时我们把编号从0~n-1，最后结果+1即为原问题的解。 (Josephus (Josephus problem) is the application of a mathematical problem: Given n individuals (with numbers 1,2,3 ... n respectively) sitting around a round table. From the number of people gettin k, number of the m man out of the line he s the next person and a number of gettin number to m the man was out of the line and so the law is repeated until the round table were all out of the column. We numbered 0 ~ n-1, the final result is the original problem solution+1 usually solve these problems.)

以一个m*n的长方阵表示迷宫，0和1分别表示迷宫中的通路和障碍。设计一个程序，对任意设定的迷宫，求出一条从入口到出口的通路，或得出没有 通路的结论 (To an m* n the long square maze, 0 and 1, respectively maze of paths and obstacles. Design a program, for any set of the maze, find a path from the inlet to the outlet, or the conclusions drawn without passage)
