maze
迷宫求解一般采用“穷举法”,逐一沿顺时针方向查找相邻块(一共四块-东(右)、南(下),西(左)、北(上))是否可通,即该相邻块既是通道块,且不在当前路径上。用一个栈来记录已走过的路径栈是限定仅在表尾(top)进行插入或删除操作的线性表。(Maze solving generally use the " exhaustive" one by one to find adjacent blocks in a clockwise direction (a total of four- East (right), South (down), West (left), North (on)) whether to pass, that the both channel blocks adjacent blocks, and not in the current path. Use a stack to record the path traversed stack is limited only in the tail (top) to insert or delete a linear form.)

HuffanCoding
读取数据,统计所得到的文件中每个字母的权值,创建哈夫曼树,哈夫曼编码。哈夫曼解码,解码后内容写入到指定的文件。
读取数据里面的内容是由英文单词组成。读取文件的时候传入文件存放的路径、读取方式以及读出以后存放的数组,最终可以得到一个存放目标文件内容的数组。
将得到的数组进行字母权值的统计,统计每个字母出现的次数,次数即为每个字母的权值。
将得到的字符数组与权值数组作为创建哈夫曼树的依据,哈夫曼树根据每个字母权值的大小来创建,每个节点,包括权值、父节点、左子、右子和字母本身。
根据哈夫曼树进行编码。形成目标文件的哈夫曼编码,将此编码返回。
根据哈夫曼树得到的数组即为解码数组,解码数组作为解码的结果返回。
写入输出文件,将解码得到的数组、文件的完整路径以及文件的写方式作为参数传入,将数组写入到相应的文件中。
(Read the data, statistical documents obtained weights for each letter, create a Huffman tree, Huffman coding. Huffman decoding, the decoded contents are written to the specified file.
Read the content inside is composed of English words. When the incoming file to read the file storage path, read mode and read out after storage array that can eventually get a storage target file contents of the array.
The resulting array of letter weights statistics, statistical number of occurrences of each letter, the number is the weight of each letter.
The resulting character array with the weights array as the basis for creating Huffman tree, Huffman tree based on the size of the weights of each letter to create, for each node, including weights, parent, left child, right child, and letter itself.
According to Huffman coding. The formation of the target file Huffman coding, this code returns.
According to Huffman decoding the resulting array is an array, the decoder decodes the result is retur)

一、 地理数据文件应用
对由点、线、面构成的地理数据文件进行打开、读取、关闭操作。
要求:
1、在C++环境下,通过程序设计实现文本格式数据文件的操作;
2、在打开数据文件后,生成点、线、面三个链表,分别用于记录三种类型的数据。
3、数据文件结构说明
(Geographic data file applications by point, line, surface consisting of geographic data file open, read, and close operations. Requirements: in C++ environment, through the program design text format data file operations 2, open the data file, generate points, lines, surfaces three linked list, respectively, for the record three types of data. 3, a data file structure)

expression
利用栈完成算术表达式求值:从键盘或文件中输入算术表达式,计算其结果并显示。要求处理过程为:(1)转换为后缀表达式并输出;(2)对后缀表达式求值并输出。
输入的表达式中可以有整数、实数、括号,运算符包括+、-、*、/、#(代表单目负)。可以多次输入不同的表达式进行计算,直到用户选择“退出”。栈的基本操作可以自己实现,也可以使用系统提供的STL实现。
(Done using an arithmetic expression evaluation stack: file input from the keyboard or an arithmetic expression, calculate and display the results. Requirements process: (1) to postfix expression and output (2) evaluation of the postfix expression and output. Enter the expression can be integers, real numbers, parentheses, operators including+,-,*,/,#( representatives unary minus). You can enter several different expressions are evaluated until the user selects " Exit." Stack can implement the basic operations, you can also use the system implementation of the STL.)

Hash-table
哈希表
数据结构课程设计
1.1问题描述
针对自己的班集体中的“人名”设计一个哈希表,使得平均查找长度不超过R,完成相应的建表和查表程序。
1.2基本要求
假设人名为中国姓名的汉语拼音形式。待填入哈希表的人名共有30个,取平均查找长度的上限为2。构造哈希函数,用链表法处理冲突。
1.3测试数据
读取熟悉的30个人的姓名作测试。(Hash table
Data Structure Course Design
1.1 Description of the problem
For their own class group of the "names" to design a hash table, making the average search length does not exceed R, the completion of construction of tables and look-up table corresponding procedures.
1.2 Basic requirements
Assuming the name of the person called Chinese pinyin form. To be filled into a hash table names a total of 30, taking the average search length of the upper limit of 2. Construct a hash function, treatment with a list of conflict.
1.3 Test Data
Read the familiar names of 30 individuals tested.)

arrangement
假设要在足够多的会场里安排一批活动,并希望使用尽可能少的会场。设计一个有效的贪心算法进行安排。(这个问题实际上是著名的图着色问题。若将每一个活动作为图的一个顶点,不相容活动间用边相连。使相邻顶点着有不同颜色的最小着色数,相应于要找的最小会场数。)
对于给定的k 个待安排的活动,编程计算使用最少会场的时间表。
(Suppose you want to arrange a number of activities in the hall more than enough, and want to use as little as possible venue. Design an effective greedy algorithm arrangements. (This problem is actually well-known graph coloring problem. If each activity as a vertex map, with the side connected between incompatible activities. Makes coloring adjacent vertices with minimum number of different colors, corresponding to looking The minimum number of venue.)
K to be arranged for a given activity, calculated using a minimum of venue programming schedule.)
