FreeTree

根据最常用的链表法进行huffman编码，可以手工预制权重，例如n=8的时候即可以在文件中写入，输出相应的编码结果(According to the most commonly used method of Chain Huffman coding, manual can be prefabricated weight, For example, n = 8 when it is written in the document, the output corresponding to the coding results)

大二时做的一个数据结构的课程设计，用2-3树实现的图书馆管理系统，只是控制台程序，没有很好的图形界面。包括管理员、读者。管理员功能有：采编入库、查看图书、查看读者、删除读者。读者功能有：借书、还书、预约、查找等等。。功能全面。包括注册账号，登录需要账号密码。(Sophomore to do a data structure of the curriculum design, with 2-3 tree implementation of library management system, but the console program, not a good graphical interface. Including administrators, readers. Administrator functions include: editing storage, check books, check readers, delete readers. Reader functions: library, book, booking, search and so on. . Full-featured. Including the registration account, login account password required. )

中科大数据结构全部上机实验的实验程序以及报告，内容包括多项式，图，栈，SQL语言……(All experimental procedures USTC data structures as well as reports on experiments, including polynomial, maps, stack, SQL language ......)

① 实现在B-树上的查找，并分析其时间复杂性。 ② 实现B-树的ADT，包括其上的基本操作：结点的加入和删除。 ③ 要求B-树结构中的M=3 或5，实现其中的一种即可。 ④ 实现基本操作的演示。 (4) 实现提示 (b-trees c/c++)

说明：  由C程序实现的 数学上 滑雪问题 的代码实现，供大家学习用(Ski problem code for all to learn to use)

本书是《程序员面试宝典》的第三版，在保留第二版的数据结构、面向对象、程序设计等主干的基础上，使用各大IT公司及相关企业最新面试题替换和补充原内容，以反映自第一版以来近几年时间所发生的变化。 　　欧立奇、刘洋、段韬编著的《程序员面试宝典》取材于各大公司面试真题(笔试、口试、电话面试、英语面试，以及逻辑测试和智商测试)，详细分析了应聘程序员(含网络、测试等)职位的常见考点。本书不仅对传统的C系语言考点做了详尽解说，还根据外企出题最新特点，新增加了对友元、Static、图形/音频、树、栈、ERP等问题的深入讲解。最后本书着力讲述了如何进行英语面试和电话面试，并对求职中签约、毁约的注意事项及群体面试进行了解析。本书的面试题除了有详细解析和答案外，对相关知识点还有扩展说明。真正做到了由点成线，举一反三，对读者从求职就业到提升计算机专业知识都有显著帮助。 　　《程序员面试宝典》适合计算机相关专业应届毕业生阅读，也适合作为正在应聘软件行业的相关就业人员和计算机爱好者的参考书。(This book is the" canon" in the third edition, retained in the second version of the data structure, object-oriented program design, main basis, the use of each big IT companies and related enterprises to the latest interview questions substitution and supplement the original content, in order to reflect the since its first edition in recent years since time changes. Ou Liqi, Liu Yang, Duan Tao," canon" drawn from major companies interview questions ( written examination, interview, telephone interview, interview, and logical test and IQ test ), a detailed analysis of the application programmer (including network, testing ) positions of the common points. This book not only to the traditional C language test done a detailed explanation, according to the new characteristics of the new foreign title, added to the friend, Static, graphics/audio, tree, stack, ERP issues in depth explanation. The last book on described how the English interview and telephone interview, and the job of signin)
