#include <iostream>
using namespace std;
int main()
{
       int num;
       cout<<"Enter the number of Stars: "<<endl;
       cin>>num;

    do {
             for(int i=0; i<num;i++)
                 {
                      cout <<" * ";
                 }

         num=num-1;
		 cout<<endl;
       
     } while( num >= 1 );


          return 0;
}
