@[cmjy](/user/716615) 这道题用九个for循环或者优化就可以
```cpp
#include <stdio.h>
int main()
{
int a,b,c;
for(a=123;a<=333;a++)
{
b=a*2;
c=a*3;
if((a/100+a/10%10+a%10+b/100+b/10%10+b%10+c/100+c/10%10+c%10==1+2+3+4+5+6+7+8+9)&&((a/100)*(a/10%10)*(a%10)*(b/100)*(b/10%10)*(b%10)*(c/100)*(c/10%10)*(c%10)==1*2*3*4*5*6*7*8*9))
printf("%d %d %d\n",a,b,c);
}
return 0;
}
```
