Answer 1

import java.util.Scanner;

public class KboatSpecialNum

{

public static int fact(int y) {

int f = 1;

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

f *= i;

}

return f;

}

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

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

int num = in.nextInt();

int t = num;

int sum = 0;

while (t != 0) {

int d = t % 10;

sum += fact(d);

t /= 10;

}

if (sum == num)

System.out.println(num + " is a special number");
