Align is the best use of the input multi-line formula in the environment, is only a personal humble opinion, because his alignment is very flexible, if we need a very smart alignment of the multi-line formula, it is recommended to use the Align

With the use of SPSS children's shoes are known, we commonly used variance analysis (ANOVA) in the general linear model (generic Linear models, called GLM) under the menu. And who is that GLM? Let's open the Magnum wiki and type the general Linear

The importance of function overloading is not clear, but you know how function overloading is implemented in C + + (although this article is about the implementation of function overloading in C + +, I think other languages are similar)? This can be

Topic Portal: http://hihocoder.com/problemset/problem/1629 The main topic: Give an N-point, M-edge of the graph, and then give the Q group to ask. Each group asks for a given interval [l,r] and asks how many pairs of points in [l,r] can reach each

There are often beginners to solve the problem of all prime numbers (prime) in N, for this, there are many answers on the internet, but many are either not professional, or only the program does not parse the algorithm, so Sanzang building to do a

The prime number is what we should all know, a count is not a prime is also very simple. The code, respectively, consists of two functions. A function implementation determines whether a number is a prime, and another function implements all primes
