研究生期间上《数值计算方法》课的作业，所有代码都是C语言实现并调试通过，现在上传为大家服务。这是带权算法-This is the assignment of numerical analysis course during my graduated education,all the codes are realized by C language,and have been debugged successfully,here I d like to share it with all of you.This one realized the algorithm of weighting

! 2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear 3 ! systems of equations by homotopy methods. There are subroutines for 4 ! fixed point, zero finding, and general homotopy curve tracking problems, 5 ! utilizing both dense and sparse Jacobian matrices, and implementing 6 ! three different algorithms: ODE-based, normal flow, and augmented 7 ! Jacobian. The (driver) subroutines called by the user are given in the 8 ! table below, and are well documented internally. The user need not 9 ! be concerned with any other subroutines in HOMPACK90. -! 2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear 3 ! systems of equations by homotopy methods.

独立于AVL库的存储媒体 虽现在有不少可用的AVL树库，但几乎都是工作在RAM中，当数据量小的时候，这种方式可行，但当树结构变大时时，读取和存储的时间就会大大变长，任务效率大大降低。能不能直接用磁盘进行树的操作呢？若可以，就不必进行频繁的磁盘内存交换了，本程序就实现了这个功能。实际上，这个程序无论是磁盘还是内存，都很好用。-independent of the AVL storage media is now available in a number of the AVL tree, But almost all work in the RAM, when a small amount of data, this approach feasible, but big tree structure constant, read and storage time will be much longer and the task efficiency has been greatly reduced. Can directly use the disk tree operation? If so, there is no need for frequent exchange of disk memory, the process to achieve this function. In fact, this procedure is disk or memory, are very handy.

没有界面，用C写的小程序 问题如下：一家软件公司招聘了数十位程序员，分成若干部门。 进行一次考试，对各个部门的所有程序员进行考核。考试结束后评出了每个人的分数。现在需要知道，在每个部门内，成绩最好的程序员和成绩最差的程序员分别是谁。输入有N+1行，每一个有若干正整数。第一行只有一个正整数，代表公司的部门数目。剩余的N行，每一行代表了该部门所有程序员的得分。其中每行第一个数字k代表了该部门的程序员个数，该行剩下的有k对数据，每对数据包括一个程序员的姓名（一个字符串）和其得分（一个正整数）。【输出形式】输出有N行，每行有两个串。第一个串该部门得分最高的程序员的姓名，第二个数字是得分最低的程序员的姓名。-no interface, written in C minor procedural issues are as follows : a software company recruited dozens of programmers, divided into several departments. An examination of the various departments for testing all programmers. Examinations in 1886 after the end of each grade. Now need to know, in every sector, but the best programmers and the worst programmers who were. N input is a line, each one a number of positive integers. There is only a first positive integer representing the number of departments. The remaining N firms, each firm on behalf of all the sector"s programmers to the basket. Each Bank figures k a representative of the number of programmers, the bank left the k right d
