#include <iostream>

using namespace std;

double  FACT_SUM (int n){

    int f , s = 0 ;

    for ( int i=1 ; i <= n ; i++){

       

        f =   ;

        s = s + f ;

       

    }

    return s  ;

}

 

 

 

int main()

{

    int n , F;

 

    cout << "hello " << endl ; 

    cout << "Pleace enter a positive number  " << endl ; 

    cin >> n ;

    if ( n > 0 ){

    F =  FACT_SUM(n-1) ;

    cout << "the answer is " <<  F <<  endl ;

    }
