刚注册，没法发帖子，我的代码第一个for循环中a[8]老随机变1677777之类的，求大佬。

```
#include <bits/stdc++.h>
using namespace std;
int main(){
for(int i=100;i<=999;i++){
if(i/100+i/10%10+i%10+(i*2)/100+(i*2)/10%10+(i*2)%10+(i*3)/100+(i*3)/10%10+(i*3)%10==45&&(i/100)*(i/10%10)*(i%10)*(i*2/100)*(i*2/10%10)*(i*2%10)*(i*3/100)*(i*3/10%10)*(i*3%10)==362880) cout<<i<<" "<<i*2<<" "<<i*3<<endl;
}
return 0;
}//懒得解释，自己看吧
