@[GodSaveJava](/user/979307) $4$ 号把 $8$ 号灯又关了，之后 $8$ 号灯又被 $8$ 号打开了。

@[GodSaveJava](/user/979307) 你后面可能理解错了，它是倍数变换，而不是平方数变换，像3，他应该还有6，4有8，5有10，变换应该是到$[a/2]+1$才只剩ai在变

对倍数的理解有误，以为是该数的n次幂。我是伞兵，此贴完结

```cpp
#include<iostream>
using namespace std;
int main(){
int n;
cin>>n;
for(int i=1;i<=n;i++){if(i*i<=n){cout<<i*i<<" ";}}
return 0;
}
```
