```cpp
#include<bits/stdc++.h>
using namespace std;
int A,B,C;
int cnt[10];
bool check(int x){
if(A == 0) return false;
if(x * B % A != 0)
return false;
int y = x * B / A;
if(C * y % B != 0)
return false;
int z = C * y / B;/*判断x:y:z 是否等于A:B:C*/
if(y < 100 || y > 999) return false;
if(z < 100 || z > 999) return false;
memset(cnt,0,sizeof(cnt));/*清空*/
int x_ = x, y_ = y, z_ = z;/*备份*/
for(int i = 1;i <= 3;i++){
cnt[x % 10] ++; x /= 10;
cnt[y % 10] ++; y /= 10;
cnt[z % 10] ++; z /= 10;
}
for(int i = 1;i < 10;i++)
if(cnt[i] != 1)
return false;
cout << x_ << ' ' << y_ << ' ' << z_ << endl;
return true;
}
int main(){
cin >> A >> B >> C;
int o = 0;
for(int x = 123;x <= 987;x++){
if(check(x))
o++;
}
if(o == 0){
cout << "No!!!";
}
return 0;
}
```
