题意: 给你一个数n(n <= 2^54),判断n是不是素数,如果是输出Prime,否则输出n最小的素因子 解题思路: 自然数素性测试可以看看Matrix67的  素数与素性测试 素因子分解利用的是Pollard rho因数分解,可以参考 Pollard rho因数分解 存个代码~ /* ********************************************** Author : JayYe Created Time: 2013-9-25 16:02:25 File Name…

题意:对于一个大整数,判断是否质数,如果不是质数输出最小质因子. 解法:判断质数使用Miller-Rabin测试,分解质因子使用Pollard-Rho,Miller-Rabin测试用的红书模板,将测试集根据matrix67的博客进行了拓展,不过也可以随机取的样子,Pollard-Rho用的kuangbin的模板. 代码: #include<stdio.h> #include<iostream> #include<algorithm> #include<string…
