多段图、遍历、排序。用C语言解决多段图中的成本问题，得出最佳优化方案。(More paragraphs figure, traverse, ranking. C language solve more paragraphs in the chart the cost, obtains the best optimization scheme. )

关于二叉树的一些相关代码，运用链表的形式，求二叉树的高度，结点个数以及叶节点个数(Some of the relevant code on the binary tree, using a linked list, find the height of a binary tree, the number of nodes, and the number of leaf nodes)

开括号和比括号的匹配，数据结构内容，很不错(More than brackets and brackets to open the match, the contents of data structure)

设有一头指针为L的带有表头结点的非循环双向链表，其每个结点中除有prev（前驱指针），data（数据）和next（后继指针）域外，还有一个访问频度域freq。在链表被起用前，其值均初始化为零。每当在链表中进行一次Locate(L,x)运算时，令元素值为x的结点中freq域的值增1，并使此链表中结点保持按访问频度非增（递减）的顺序排列，同时最近访问的结点排在频度相同的结点的最后，以便使频繁访问的结点总是靠近表头。试编写符合上述要求的Locate(L,x)运算的算法，该运算为函数过程，返回找到结点的地址，类型为指针型。(Has a head pointer is non-circular doubly linked list L with a header node, each node in addition to prev (precursor pointer), data (data) and next (successor pointers) outside, there is an access frequency degree domain freq. Before the list was hired, their values are initialized to zero. Whenever carried out in the list once Locate (L, x) when the operation, so that the element node x is the value in freq domain by one, and keep this list in the node-access frequency of non-increasing (decreasing) the order, while a recent visit to the nodes in the same row of the frequency of the last node, so that the nodes are frequently accessed tables are always near the head. Locate (L, x) algorithm is prepared in accordance with the above requirements of the test operation, the operation as a function of the process, return to find the address of the node of type pointer.)

对于给定的n个字符串，请找出一种最佳的连接方式，使得采用该连接方式得到的字符串在所有连接的结果中，字典序最小(For a given n-string, find an optimal connection, making use of the connection string to get the results in all connections, the lexicographic minimum)

说明：  一个实现外部排序的程序，其中gnerate.cpp为产生一个随机的文件，用于被排序。而caculate.cpp为外部排序程序。(A realization of the external sort program, which gnerate.cpp to generate a random file for be sorted. The caculate.cpp external sort program.)

数据结构与算法分析的 C++检索代码，很经典(the code of Data structure)

图的遍历的实现，文字界面，包含深度遍历和广度遍历两种情况~~(Graph traversal implementation, the text interface, including the depth and breadth traversal traverse both cases ~ ~)

包含了数据结构实现堆栈的方法。 主要有链表实现和数组实现以及堆栈的应用。(This pakcet inclues the programs to implement the stack with chain and array and it s application.)

纯C语言编程的模拟现有图书馆的借阅、续借、归还；图书入库、出库；查询、排序等功能，实现电子图书馆的智慧综合管理。其中查询功能里面嵌套精确查询，排序功能有六种，界面可变色，里面已经附带50多本图书信息包括图书摘要等详细信息。里面还附带详细设计报告和解说PPt。(Pure C language programming simulation existing library borrow, renew, return book storage, a library queries, sorting and other functions, to achieve integrated management of electronic library wisdom. Precisely where the query function inside a nested query, sort function has six, the interface can change color, which has included more than 50 books including books summary information and other details. Which also included detailed design reports and commentary PPt.)
