没加换行```cpp
#include<bits/stdc++.h>
using namespace std;
int s1(int a)
{
int v=a;
int d=a;
int sum=0;
sum=(a/100)%10+(d/1000)%10*10+(v/10000)*100;
return sum;
}
int s2(int b)
{
int v=b;
int d=b;
int sum=0;
sum=(b/10)%10+(d/100)%10*10+(v/1000)%10*100;
return sum;
}
int s3(int c)
{
int v=c;
int d=c;
int sum=0;
sum=c%10+(d/10)%10*10+(v/100)%10*100;
return sum;
}
int main()
{
int k;
cin>>k;
for(int i=10000;i<=30000;i++)
{
if(s1(i)%k==0&&s2(i)%k==0&&s3(i)%k==0)
{
cout<<i<<endl;
}
}
}

@[xiaochangyu](/user/792613) 首先，你忘记换行了，其次，题目中说了，如果无解，则输出“No”。这两个你都忘了。

没加换行和NO
```cpp
#include<bits/stdc++.h>
using namespace std;
bool scp=0;
int s1(int a)
{
int v=a;
int d=a;
int sum=0;
sum=(a/100)%10+(d/1000)%10*10+(v/10000)*100;
return sum;
}
int s2(int b)
{
int v=b;
int d=b;
int sum=0;
sum=(b/10)%10+(d/100)%10*10+(v/1000)%10*100;
return sum;
}
int s3(int c)
{
int v=c;
int d=c;
int sum=0;
sum=c%10+(d/10)%10*10+(v/100)%10*100;
return sum;
}
int main()
{
int k;
cin>>k;
for(int i=10000;i<=30000;i++)
{
if(s1(i)%k==0&&s2(i)%k==0&&s3(i)%k==0)
{
cout<<i<<endl;
scp=1;
}
}
if(scp==0) printf("No");
}
```
