Question

write a Java program to find the sum of series.
1!/1 +2!/2 +3!/3 + n!/n
please give answers fast it's urgent..​

Answer 1

Answer:

Program:-

//Program using Scanner class

import java.util.*;

public class Brainly_Answer

{

public static void main(String args[ ])

{

Scanner in=new Scanner(System.in);

int i,j,n;

double s=0;

System.out.println("Enter limit:");

n=in.nextInt();

for(i=1;i<=n;i++)

{

int fact=1;

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

{

fact=fact*j;

}

s=s+fact/(double)i;

}

System.out.println("The sum of the given series="+s);

}

}

• The first photo is the program.
• The second photo is the input i.e 3. I entered three so that you can also calculate it easily by checking.(1+1+2=4)
• The third photo is the output that I have checked it's right.
• The fourth photo is the input ,I entered 5
• The fifth photo is the output that I also checked(4+6+24).

Sorry I can't type 'f' so I changed it as 'fact' otherwise in brainly it's showing error.
