I love learning, learning makes me happy.But maths makes me vomit blood.This article will be a rough summary of some basic number theory knowledge, and the blogger has done a number of mathematical knowledge of high-demand topics.But so far, bloggers have nothing to do, so there's basically nothing here.First, Euclidean algorithmSecond, expand Euclidean algorithm

1/p = x/K, then our proposition is proved.. To prove this conclusion, we need to reference the ferma's theorem, See:Baidu Encyclopedia: http://baike.baidu.com/view/263807.htm The ferma's theorem is an important theorem in number theory. Its section contains:If P is a prime number and (A, P) = 1, then a ^ (p-1) 1_1 (mod P) Suppose P is a prime

Although this book has many ArticleSome people have recommended this, but I still want to like it, because this is my own . This book is written by John E. hopcroft, Rajeev motwani, Jeffrey D. Ullman. Introduction to automata theory, ages, and computation. When I first read this book He thinks that the basic method

will be followed by a line containing zero. OutputFor each test case, output a single integer on a line by itself-the number of seconds you and your friend need between the time he leaves the jail cell and the time both of you board the train. (assume that you do not need to wait for the train-they leave every second .) if there is no solution, print "back to jail ". Sample Input Sample output 211 2 999331 3 102 1 203 2 509121 2

Recently I read the number theory and re-thought about this question. I referred to the paper and the lrj black book, re-proved it, and made a note. Example: hdoj 1792 a new change problemGiven the interconnectivity between A and B, A and B, the maximum and maximum numbers cannot be combined. Basic knowledge:Gcd (a, B) = 1 → lcm (a, B) = ABThe remainder class, wh

Obtain the prime number by using the screening method of the unique factorization theorem of ultraviolet A 10375.

In othe

The basic content of the unique decomposition theory: Any positive integer greater than 1 can represent the product of several prime numbers, and the representation method is unique. In other words, a number can be uniquely divided into the product of a prime factor. Therefore, this theorem is also called the unique decomposition theorem. Example: 50 = (2 ^ 1) * (5 ^ 2) The general idea of the question is t

Prime Number in number theory learning 1. Definitions: Division: Set A and B to two integers, and B! = 0 if there is an integer c that makes a = BC, it is said that a is divided by B, or B is divided by a, it is recorded B |; Division with remainder: A = QB + R; This formula is called the remainder of the records with Division R = a mod B; 2.
