如果是素数直接输出1与素数,否则枚举长度和起始数即可. #include<cstdio> #include<cstring> #include<cmath> #include<vector> #include<map> #include<queue> #include<stack> #include<algorithm> using namespace std; long long n; bool prime(…

题意:一个正整数n可以分解成一系列因子的乘积,其中会存在连续的因子相乘,如630=3*5*6*7,5*6*7即为连续的因子.给定n,让你求最大的连续因子个数,并且输出其中最小的连续序列. 比如一个数可以分解2*3*4*6*7*8,最大的连续个数为3,因为存在两个,输出最小的那个即2*3*4. 首先,一个数如果是合数,那么它的因子必定不会超过sqrt(n)或者sqrt(n)+1.如果为质数,那么只可能为自己,因为题目说了不包括1. 我们先将2~sqrt(n)+1中为n的因子存到factor数组中,…

题意: 输入一个int范围内的正整数,输出它最多可以被分解为多少个连续的因子并输出这些因子以*连接. trick: 测试点5包含N本身是一个素数的数据,此时应当输出1并把N输出. 测试点5包含一个2e9以上的int整数,此时最好把n当作long long 否则以下代码会运行超时. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ][]; int main()…

题目 Cutting an integer means to cut a K digits long integer Z into two integers of (K/2) digits long integers A and B. For example, afer cutting Z = 167334, we have A = 167 and B = 334. It is interesting to see that Z can be devided by the product of…

题目 For two rational numbers, your task is to implement the basic arithmetics, that is, to calculate their sum, diference, product and quotient. Input Specification: Each input file contains one test case, which gives in one line the two rational numb…
