UVA10006 - Carmichael Numbers（筛选构造素数表+快速幂） 题目链接 题目大意：如果有一个合数，然后它满足任意大于1小于n的整数a， 满足a^n%n = a;这样的合数叫做Carmichael Numbers。题目给你n，然你判断是不是Carmichael Numbers。 解题思路：首先用筛选法构造素数表，判断n是否是合数，然后在用快速幂求a^2-a^(n

题目： An important topic nowadays in computer science is cryptography. Some people even think that cryptography is the only important field in computer science, and that life would not matter at all wi
