40分，大佬们帮忙看看 TOT

#include <bits/stdc++.h>
using namespace std;
int main(){
    int A,B,C;
    cin>>A>>B>>C;
    int sum1;
    for(int i = 100;i<=333;i++){
        int a = i*A , b = B*i , c = C*i , vis[10] = {0} , sum = 0;
        vis[a/100] = vis[a/10%10] = vis[a%10] = 1;
        vis[b/100] = vis[b/10%10] = vis[b%10] = 1;
        vis[c/100] = vis[c/10%10] = vis[c%10] = 1;
        for(int j = 1;j<=9;j++) sum+=vis[j];
        if(sum==9) cout<<a<<" "<<b<<" "<<c<<endl;
        sum1 = sum;
    }
    if(sum1) cout<<"No!!!";
    return 0; 
}
