期末考试日程管理系统，代码免费公开，做的有点大，有4M多了，没办法功夫不到家...

在班级，年级范围查询成绩，可以增加，删除记录-class, grade scope of inquiry results, can add, delete records

稀疏矩阵的十字链表算法-sparse matrix algorithm Cross Chain

三种排序方法的动态演示，可以同时开启多个线程，同时用不同的方法进行排序，直观的判断不同算法的排序效率。-three sequencing method of dynamic presentations, it also opened a number of threads, in addition to the use of different methods for sequencing, intuitive judgment different sorting algorithms efficiency.

设计邻接表类,实现无向图的深度优先非递归遍历,无向图的广度优先遍历,并设计主函数输入数据进行测试-Design category adjacency list, realize undirected graph of the depth-first traversal non-recursive, non-directed graph breadth-first traversal, and the design of the main function of the input data for testing

在视频处理中经常要用到Zigzag序号及其逆序号，本文提供了一个新的类CZigzag，可以求任意m×n块的Zigzag序号及其逆序号。 由于所求的Zigzag序号及其逆序号为一次性遍历生成，其时间复杂度仅为O（m×n）。-In video often use to deal with the serial number and its reverse No. Zigzag, the paper provides a new category CZigzag, can seek arbitrary m × n block Zigzag its serial number and its reverse. Zigzag As the demand for its serial number and its reverse traversal generates one-time, its time complexity is only O (m × n).

零件切割问题： 给定一块宽度为W的矩形板，矩形板的高度不受限制。现需要从板上分别切割出n个高度为hi，宽度为wi的矩形零件。切割的规则是零件的高度方向与矩形板的高度方向保持一致。问如何切割使得所使用的矩形板的高度h最小？ 任给一个输入实例，能输出切割所需要的实际高度并能用图形演示切割的过程-cutting parts : a given width of the rectangular plate W, the height of rectangular plate unrestricted. Need from the board is cutting out respectively n height of the hi, wi width of the rectangular parts. Cutting parts to the rules of the height of the rectangular plate with a high degree of consistent direction. Asked how cutting makes use of the rectangular plate height h minimum? As an input for example, will cut output by the needs of the high and can be used graphic demonstration of the cutting proce

给定n 个整数a ,a , ,an 1 2  组成的序列， a n i | |£ ，1 £ i £ n。如果对于i £ j ，有 0 = å = j k i k a ，则称序列区间i i j a , a , , a +1  为一个零和区间，相应的区间长度为j-i+1。-given n integers a, a, and an 1 2
