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!)

Dijlstra算法 对任意图，选择合适的数据结构表示图，在此基础上实现求解最短路径的Dijkstra算法(Dijlstra algorithm to arbitrary map, select the appropriate data structures that map, on this basis to achieve solution of the Dijkstra shortest path algorithm)

图中计算最短路径，必须覆盖所有的节点，效率很高(to compute the shortest path in the graph)

代码注重B树插入、删除的算法逻辑，适用于 学习者研究B树实现的核心思想。代码中无庞杂的无关操作(focus on B-tree code insertion, deletion algorithm logic applies to B-tree research learners to achieve the core idea. The code has nothing to do with the complex operation )

POJ 字符串的插入 可以将一定长度的字符串插入之前给出的字符串之中(POJ string can be inserted into a length of string into a string before being given)

上海交通大学数据结构课程的课后作业系列3.5：仅供参考，最好还是自己去写(Shanghai Jiaotong University data structure course homework Series 3.5: for reference, it is best to write their own)

约瑟夫问题，用数据结构的循环链表实现约瑟夫问题的解答(Joseph problems，30 people in a circle, and inspires us with a circular chain to said. Can use structure array to make a cycle chain. The structure has two members, one for pointing down a pointer to a circular chain )

利用栈完成算术表达式求值：从键盘或文件中输入算术表达式，计算其结果并显示。要求处理过程为：（1）转换为后缀表达式并输出；（2）对后缀表达式求值并输出。 输入的表达式中可以有整数、实数、括号，运算符包括+、-、*、/、#（代表单目负）。可以多次输入不同的表达式进行计算，直到用户选择“退出”。栈的基本操作可以自己实现，也可以使用系统提供的STL实现。 (Done using an arithmetic expression evaluation stack: file input from the keyboard or an arithmetic expression, calculate and display the results. Requirements process: (1) to postfix expression and output (2) evaluation of the postfix expression and output. Enter the expression can be integers, real numbers, parentheses, operators including+,-,*,/,#( representatives unary minus). You can enter several different expressions are evaluated until the user selects " Exit." Stack can implement the basic operations, you can also use the system implementation of the STL.)

选择排序的实现，是一种基本的排序方法，但是时间复杂度相对较大。(Select Sort realization, is sort of a basic, but relatively large time complexity.)

USACO中的American heritage，用C++编写，运用了树的遍历知识(the American heritage of USACO, with C++ prepared, using a tree traversal knowledge)
