给一个整数n,问是否存在3个不同的数a,b,c,a,b,c, 2≤a,b,c,a⋅b⋅c=n2≤a,b,c,a⋅b⋅c=n,如果存在输出yes,并输出任一满足的三个数,否则输出no 思路:# 将n进行质因子分解,然后进去讨论判断即可,具体看代码 代码:# Copy#include <iostream> #include <stdio.h> #include <algorithm> ...

Product of Three Numbers CodeForces - 1294C (思维,质因数分解),题意:给你一个整数n。找出三个不同的整数a、b、c,使得2≤a、b、c和a⋅b⋅c=n,或者说这是不可能的。如果有几个答案,你可以打印任何答案。题解:很容易看出来这是道质因数分解,我们只需要在分解
