我的程序你可以参考一下我这个是过掉了的
```cpp
#include <iostream>
#include <cstring>
#include <algorithm>
using namespace std;
int i,k;
bool f;
int main()
{
cin>>k;
for (i=10000;i<=30000;i++)
{
if(i/100%k==0)
{
if((i/10-i/10000*1000)%k==0)
{
if((i-i/1000*1000)%k==0)
{
cout<<i<<endl;
f=1;
}
}
}
}
if(!f) {cout<<"No";}
//system("pause");****
return 0;
}
```

```cpp
#include<iostream>
#include<cstdio>
#include<cstring>
#include<cmath>
using namespace std;
int arr[10010000];
int main() {
long long z=1,s=0,i,j,m,n,k,a,b,c;
cin>>n;
if(n==1){
for(i=10000;i<=30000;i++)
cout<<i<<endl;
return 0;
}
for(i=10000; i<=30001; i++) {
a=i/100;
m=i%10000/10;
j=i%1000;
if(a%n==0&&m%n==0&&j%n==0) {
s++;
cout<<i<<endl;
}
}
if(s==0){
cout<<"No";
}
return 0;
}
