链接: https://vjudge.net/problem/LightOJ-1282 题意: You are given two integers: n and k, your task is to find the most significant three digits, and least significant three digits of nk. 思路: 后三位快速幂取余,考虑前三位. \(n^k\)可以表示为\(a*10^m\)即使用科学计数法. 对两边取对数得到\(k*log…
题目描述 输入b,p,k的值,求b^p mod k的值.其中b,p,k*k为长整型数. 输入输出格式 输入格式: 三个整数b,p,k. 输出格式: 输出“b^p mod k=s” s为运算结果 作为初学者,还是应当用简洁的方法和代码(我认为很简洁),废话不说,直接看代码: #include<iostream> #include<cstdio> #include<cmath> using namespace std; long long x(long long int a…
