c语言版的多项式曲线拟合。 用最小二乘法进行曲线拟合. 用p－1 次多项式进行拟合，p<= 10 x,y 的第0个域x[0],y[0],没有用，有效数据从x[1],y[1] 开始 nNodeNum,有效数据节点的个数。 b,为输出的多项式系数，b[i] 为b[i-1]次项。b[0],没有用。 b,有10个元素ok。

高精度乘法基本思想和加法一样。其基本流程如下： ①读入被乘数s1，乘数s2 ②把s1、s2分成4位一段，转成数值存在数组a,b中；记下a,b的长度k1,k2； ③i赋为b中的最低位； ④从b中取出第i位与a相乘，累加到另一数组c中；（注意：累加时错开的位数应是多少位 ？） ⑤i:=i-1；检测i值：小于k2则转⑥,否则转④ ⑥打印结果

Input The input consists of two lines. The first line contains two integers n and k which are the lengths of the array and the sliding window. There are n integers in the second line. Output There are two lines in the output. The first line gives the minimum values in the window at each position, from left to right, respectively. The second line gives the maximum values. Sample Input 8 3 1 3 -1 -3 5 3 6 7 Sample Output -1 -3 -3 -3 3 3 3 3 5 5 6 7

The initial planning and thinking about this book began during a discussion of SQL Server futures in July 2001. The discussion was with Rob Howard during a trip to Microsoft to discuss the first book I was working on at that time. After that, I stayed involved in what was happening in ADO.NET by going to the SQL Server Yukon Technical Preview in Bellevue, Washington, in February 2002 and by working with the ASP.NET and SQL Server teams at Microsoft since July 2003.

Using Gaussian elimination to solve linear equations. // In this version, we allow matrix of any size. This is done by treating // the name of a 2-dimensional array as pointer to the beginning of the // array. This makes use of the fact that arrays in C are stored in // row-major order.

分数是两个整数的比，通常表示为 (或b/a)的形式，其中b称为分子，a称为分母，分母不能为0。分数在计算机中以整数或浮点数（有限小数）的形式表示，大多数情况下都是近似表示，具有较大的误差，例如 ，在计算机中用整数表示为0，用浮点数表示为0.333333。本实例就是要设计一个Fraction (分数) 类类型，该类型的对象可以像基本类型数据一样进行运算，结果仍为分数，运算包括四则运算，关系运算，及求一元一次分式方程的解，输入输出要求按分数方式进行。

This document represents the first stage in a process of taking the National Strategy for Police Information Systems (NSPIS) forward. It defines the mechanisms to ensure that we (and our partners) have access to the right information, in the right form, in the right time at an appropriate cost. The Strategy will ensure the Police Service has a collective understanding of the value of information and that we are able to exploit National Information Assets in support of local policing.

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如，1，2， 5，10 都是正整数10 的约数，且div(10)=4。设a 和b 是2 个正整数，a≤b，找出a 和b 之间约数个数最多的数x。
