KD-tree

说明：  任意给定输入的一个小写英文字符串a1a2a3…an-1an (n≥5) 输出：字符串Ana1An-1a2An-2a3…A2an-1A1an,其中Ai为ai的大写形式 例如，输入aybdx，则递归程序输出XaDyBbYdAx (Any given input of a lowercase string a1a2a3 ... an-1an (n ≥ 5) Output: the string Ana1An-1a2An-2a3 A2an-1A1an, which Ai ai uppercase for example, input aybdx recursive program output XaDyBbYdAx)

题意:给你n个数,求出两两组合的最大公约数 类似打素数表的做法 (Meaning of the questions: to give you the number n, find greatest common divisor of a similar combination twenty-two hit the practice table of prime numbers)

二叉树实现，整个包为VS工程。包含了二叉树的基本功能(Binary Tree, the entire package is VS works. Contains the basic functions of the binary tree)

二叉树的中序遍历，先序遍历以及后序遍历的算法(Binary tree in preorder traversal, preorder traversal and postorder traversal algorithm)

图的邻接表生成，深度遍历及任意两点间的路径(The adjacency table to generate deep traversal path between any two points)

任务：实现Dijkstra算法 工程名：Project_ShortestPath 要求：实现Dijkstra算法，算法主体写在CGraph类中；要求是从command窗口中输入源节点编号，并在command窗口中输出从源节点到所有目的节点的最短路长及最短路。注：要输出整条路径，而不仅仅是前一跳，也不允许逆序输出。 (Task: Dijkstra' s algorithm to achieve the project name: Project_ShortestPath requirements: achieve Dijkstra algorithm, the algorithm written in the body CGraph class requires input from the command window, the source node number, and in the command window, all of the output from the source node to the destination node shortest long and the shortest. Note: To export the entire path, not just before the jump, do not allow reverse output.)

设计一个表达式求值的程序。该程序必须可以接受包含（，），+，-，*，/的中缀表达式，并求出结果。如果表达式正确，则输出表达式的结果；如果表达式非法，则不输出或输出其他字符。(Design an expression evaluation procedures. The program must accept (,), including +, -, *, / the infix expression, and the results obtained. If the expression is correct, the output of the expression is output; if the expression is illegal, no other characters are output or exported.)

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)
