AC,求关

（用next_permutation很方便）

#include<bits/stdc++.h>
using namespace std;
int main(){
    int A,B,C,a[9]={1,2,3,4,5,6,7,8,9};
    cin>>A>>B>>C;
    bool f=0;
    do{
        int x=a[0]*100+a[1]*10+a[2];
        int y=a[3]*100+a[4]*10+a[5];
        int z=a[6]*100+a[7]*10+a[8];
        if(x*B==y*A && y*C==z*B)
        cout<<x<<" "<<y<<" "<<z<<endl,f=1;
    }while(next_permutation(a,a+9));
    if(f==0)cout<<"No!!!";
    return 0;
}
