How to rewrite the Russian square in C and the Russian square in CI used to write a Tetris in C language, but I haven't read the program since I wrote it. The source code is too bad for anyone to read. I also posted the source code on the Internet. I really don't know what I think. Maybe it was the first time I wrote a program that I always wanted to write. So I'm very excited. I believe that many people wh

If P = 2 or P = 4 * k + 1, P can be expressed in the form of the sum of two degrees (Euler and ferma have proved and have an exact method). Therefore, the answer is P. If P = 4 * k + 3, set a ^ 2 = N (mod p) (n! = 0) it can be proved that there is no B, B ^ 2 = p-n (mod p). That is, if n is the square residue of p, p-n is not the square residue of P. Proof: because a ^ 2 = N (mod P), N ^ (p-1)/2) = 1 (mod

Written in 2012.10:Originally this is rectification that "C Program Design (fourth edition)" of a after class exercises, just start to do when to find the best algorithm on the Internet, the results found that odd and double even (4 multiples) of the case algorithm is relatively simple, But a single even number ( a multiple of 2 but not a multiple of 4) has been unable to find a definite algorithm, even the Baidu Encyclopedia of the explanation of the problem is " because the non-four multiple

1 mean value The mean value represents the size of the DC component in the signal, expressed in E (x). For a Gaussian white noise signal, its mean value is 0, so it has only the AC component. 2 square of the mean value The square of the mean, denoted by {E (x)}^2, represents the power of the DC component in the signal. 3 mean square value The mean

Chi-square test is a hypothesis test method for counting data with a wide application. It belongs to the category of Nonparametric test, which mainly compares the correlation analysis of two and over two sample rate (composition ratio) and two categorical variables. The fundamental idea is to compare the theoretical frequency with the actual frequency of the degree of coincidence or goodness of fit problem. (More reference: chi-

The dilemma of object-oriented methods -- a square cannot inherit from a rectangle? Http://blog.csdn.net/javayuan/article/details/1191751 () At the beginning of object-oriented theory, inheritance abuse is often caused by lack of guidance from best practices. A famous example is that the Stack class Stack in the Java class library inherits the Vector class.Public class Stack extends vector ...{ Public object push (Object item )...{ Addelement (item );

An exercise for Scip 1.1.7. The Newton's method is also called the Newton-Raphson method ), it is an approximate method proposed by Newton in the 17th century to solve equations in real and complex fields. Most equations do not have root formulas, so it is very difficult or even impossible to find the exact root, so it is particularly important to find the approximate root of the equation. Methods The first few items of the Taylor series of function f (x) are used to find the root of the equatio
