题目 Among all the factors of a positive integer N, there may exist several consecutive numbers. For example, 630 can be factored as 3*5*6*7, where 5, 6, and 7 are the three consecutive numbers. Now given any positive N, you are supposed to find the ma…

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()…

题意: 给出一个正整数N,找到最长的连续的可分解因子.如N=630,可被分解为630=3*5*6*7,其中5*6*7是3个连续的因子. 思路: 首先,需要明确,对于任何一个整数,如果它是素数,则不可被分解,因子只有1和其本身:如果它是合数,则除了1和本身之外,它的因子必然是在sqrt(n)两侧成对出现的,此时,这些质因子要么全部小于等于sqrt(n):要么只存在一个质因子大于sqrt(n),而其他质因子全部小于sqrt(n).因此我们只需要考虑2~sqrt(N)的范围即可.对于每一个i∈[2,s…
