import java.util.Scanner;
public class KboatSDAPrime

public void number(int a[]) {
System.out.println("Numbers whose sum of digit is prime:");
for (int i = 0; i < a.length; i++) {

int s = 0;
while (x != 0) {
int d = x % 10;
s += d;
x /= 10;
}
int c = 0;
for (int j = 1; j <= s; j++) {

public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter the number of elements: ");
int n = in.nextInt();
int arr[] = new int[n];
System.out.println("Enter array elements: ");
