#include<iostream>
using namespace std;

int main()
{
    int i,j,a[101]={0};
    for(i=1;i<101;i++)for(j=1;j<=i;j++)if(i%j==0)a[i]=a[i]+1;求每数因数个数
    int b[101]={0};  
    for(i=1;i<101;i++)b[i]=b[i-1]+(a[i]%2); 求<=i且因数数为奇的数的个数  
    
    int k,c[101]={0};
    cin >>k;
    for(i=0;i<k;i++)cin >>c[i];
    for(i=0;i<k;i++)cout <<b[c[i]]<<endl;
    cin >>i;
}
