归并排序,复习排序算法，在不同环境下，寻找时间复杂度最少的排序算法( Merge sort, review sorting algorithm, in different contexts, looking for the least time complexity of sorting algorithm)

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：  用链表的方式实现多项式的加减，其中结构体包含幂次和系数。(Polynomial addition and subtraction with a list of ways in which the structure and contains the power of coefficients.)

迷宫问题C++代码。。。解决迷宫问题。。。。(Maze C++ code. . . Solve maze problems. . . .)

建立试题库文件，随机产生n个题目； 题目涉及加减乘除，带括弧的混合运算； 利用栈求解表达式的值； 随时可以退出； 保留历史分数，能回顾历史，给出与历史分数比较后的评价( The establishment of test database file, the subject of n randomly generated topics related to addition, subtraction, mixed operations with parentheses use the value of the expression stack solution ready to quit to preserve the historical scores, can look back at history, and history gives the comparison of scores Evaluation 保留历史分数，能回顾历史，给出与历史分数比较后的评价)

常在该网站下载资料，也想分享些材料上去，这个资料是FRFT算法(Often the site to download information, but also want to share some material up, this information is FRFT algorithm)

mfc 连接数据库 用mfc做的管理系统，戏中包括数据库连接(mfc connect to the database)

说明：  给定程序中，函数fun的功能是：将a所指3×5矩阵中第k列的元素左移到第0列，第k列以后的每列元素依次左移，原来左边的各列依次绕道右边。 例如，有以下矩阵： 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 若k结果为2，程序执行结果为： 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 请在程序的下划线处填入正确的内容并把下划线删除，使程序得出正确的结果。 注意：源文件存放在考生文件夹下的BLANK1.C中 不得增行或删行，也不得更改程序的结构！ (A given program, function fun feature is: a 3 × 5 matrix referred to in the first k elements of the left column to move Section 0, the k elements of each column after column followed by the left, the original columns in the left turn Bypass on the right. For example, the following matrix: 123,451,234,512,345 If k is 2, the program execution results: 345,123,451,234,512 in the program underscore the right content at the fill and to remove the underscore, so that the program reach the right result. Note: The source files in the folder of BLANK1.C candidates are not allowed by the line or delete line, nor change the structure of the program!)

排序二叉树（模板类），主要用于数据排序和查找。已在项目中使用(Sorted binary tree (template class), mainly used for data sorting and searching. Has been used in the project)

数字根算法，用最简单的代码计算数字根。如果把一个大数的各位数字相加得到一个和，再把这个和的各位数字相加又得一个和，再继续作数字和，直到最后的数字和是个位数为止，这最后的数称为最初那个数的“数字根”。(Digital root algorithm, with the most simple code to calculate the digital root. If you figure in a large numbers is the sum of a, then this and you figure the sum is again a, and then continue for digital and until the final figure and the single digits, the last number called initially that the number of "digital root".)
