用C做的括号匹配程序,可以检测用户输入的括号是否匹配并给出提示-C matching brackets do procedures, the user can input the brackets and whether the match is suggested

清华大学数据结构课上实现的B+树，设计一个4阶B+树，包括： (1) 叶子的每个记录应该包括4字节（long）关键码值和60字节的数据字段(存储文件名等，可以自定)，设每个叶子可以存储5条记录，而内部节点应该是关键码值/指针对。此外，每个节点还应该有指向同层下一个节点的指针、本节点存储的关键码数等； (2) 此4阶B+树应该支持插入、删除以及根据给定关键码值进行精确检索与关键码范围检索； (3) 显示（打印）此4阶B+树的生长(含删除节点)过程实例；-Tsinghua University class data structure to achieve the B-tree, the design of a B-tree four bands, including : (a) the leaves of each record should include 4-byte (long) key code value and 60 gigabytes of data fields (document storage, etc., can be set), set up each leaf store five records, and internal nodes is the key code value/means against. In addition, each node should have the same point under a layer of the target node, the node storage key code number; (2) The B-tree four bands should support the insertion, deletion and with the given key code value accurate retrieval and key codes scope retrieval; (3) Display (Print ) This four bands B-tree growth (including the deletion of nodes) process examples;

在这段代码中，您将学习如何使用PHP/MySQL上传图像。

包括快速排序、堆排序、合并排序等经典算法，有详细的说明，供初学者学习

这是一份实验报告，用以验证和实现插入删除查询排列等数据库语言操作。-This is a test report to verify and insert a delete query to achieve ordered operations such as database language.

由系统随机建立一个迷宫,然后屏幕输出路径。为在完成作业的同时复习所学过的内容,完成一条路径的时候用到了递归的方法 而做全部路径的时候用非递归的方法。用户界面友好，有用户使用说明.每一步操作都有说明与提示。程序运行通过，有详细的解释说明-system by the establishment of a random maze, and then screen output path. For the complete review of operations at the same time have learned from the contents of a complete path of the use of recursive method to do all the time path of non- recursive method. User friendly interface, users note. Every step of the operation have notes and hints. Running through a detailed explanation of
