其实就这样！！

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,m;cin>>n>>m;
    int a[n];
    for(int i=1;i<=n;i++)a[i]=0;
    cout<<"1";
    for(int i=2;i<=n;i++)
        for(int j=2;j<=m&&j<=i;j++)
            if(i%j==0)a[i]=!a[i];
    for(int i=2;i<=n;i++)
        if(a[i]==0)cout<<" "<<i;//是“ ”不是“，”
}
