一、原理 欧几里得算法(Euclidean Algorithm)又称辗转相除法,用于计算求两个非负整数的最大公约数,欧几里得算法一定可以在有限步内完成。 辗转相除法基于原理“两个整数的最大公约数等于其中较小值与两数相除余数的最大公约数”,即“Greatest Common Divisor (GCD)递归原理”,用公式表示为: GCD(a,b)=GCD(b,a%b...
采用Euclid's算法时,不仅要r(余数)的值,还需要q(商)的值。 本例实现参考了Wikipedia中介绍的迭代方法:http://en.wikipedia.org/wiki/Extended_Euclidean_algorithm /** * * @author ljs 2011-5-17 * * solve extended gcd using Euclid's Algorithm and Iterative Method * */ publicclassExtGCD_Euclid {...
辗转相除法, 又名欧几里德算法(Euclidean algorithm)乃求两个正整数之最大公因子的算法。 算法示意图 递归法 int getGcd(int a, int b) { return b == 0 ? a : getGcd(b, a % b); } 示例代码 #include <stdio.h> #include <math.h> int getGcd(int a, int b) { return b == 0 ? a...
In this challenge, we learn how to compute GCD using the Euclidean algorithm. Resources Here's a helpful video on the topic: Given two integers,and, a recursive technique to find their GCD is theEuclidean Algorithm. The algorithm states that, for computing the GCD of two positive integersand...
