Sorry for my poor English!:)
Here is my program:
#include<iostream.h>
int main()
{
 freopen("financial.in","r",stdin);
 freopen("finiancial.out","w",stdout);
 int testcase;
 cin>>testcase;
 int i,m,n;
 bool flag;
 for (int t=1;t<=testcase;t++)
   {
    cin>>n;
    m=1;
    while (n%2==0)
      {
       n=n>>1;
       m+=1;
      }
    if ((m%2==1) && (n>1))
      cout<<"YES"<<endl;
    else {
          flag=false;
          for (i=2;i<=n-1;i++)
            if (n%i==0)
              {
               flag=true;
               break;
              }
          if (flag) cout<<"YES"<<endl; else cout<<"NO"<<endl;
         }
   }
 return 0;
}

if answer is 1*9=9
then look this

9

1) 9=1*3*3 => answer="NO"
2) 9=1*9   => answer="YES"
Thanks
