WHY PE#include"iostream"
using namespace std;
int main()
{
bool st[1100]={false};
int i=2;
int j=2;
int a[200];
for(i=2;i<=500;i++)
{
j=2;
while(i*j<=1100)
st[i*j++]=true;
}
j=0;
for(i=1;i<1100;i++)
if(!st[i]) a[j++]=i;
int n,m;
while(cin>>n>>m)
{
cout<<n<<" "<<m<<" :";
for(i=0;;i++)
{
if(a[i]>n) break;
}
if(2*m-1>=i)
for(j=0;j<i;j++)
cout<<" "<<a[j];
else
if(i%2==0)
for(j=i/2-m;j<i/2+m;j++)
cout<<" "<<a[j];
else
for(j=i/2-m+1;j<i/2+m;j++)
cout<<" "<<a[j];
cout<<endl<<endl;
}
return 0;
}
我再ZOJ是WA,再这里交是PE,检查了N小时了,还是不知道错了,哪位帮我看下好吗?
