Answer»

Explanation:

import java.util.*;

public class menu-driven {

public VOID main () {

Scanner sc=new Scanner(System.in);

System.out.println("1."+" Sum=1+4+27+256.......... to n terms");

System.out.println("Enter your CHOICE :");

int ch=sc.nextInt();

case 1:

System.out.println("Enter the value of n");

int n=sc.nextInt();

int sum=0;

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

sum=sum+(Math.Pow(i,i));

}

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

break;

default:

System.out.println("INCORRECT choice");

}
