import java.util.Scanner;

public class KboatSeries

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter n: ");

int n = in.nextInt();

double sum = 0.0;

for (int i = 2; i <= n; i++) {

double num = 0.0, den = 1.0;

for (int j = 1; j <= i; j++) {

num += j;

den *= j;

}

sum = sum + (num / den);

}

System.out.println("Sum=" + sum);
