Question

Accepted Answer

import java.util.Scanner;

public class KboatSpecialNum
{
    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, fact;
        while (t != 0) {
            int d = t % 10;
            fact = 1;
            for (int i = 1; i <= d; i++) 
                fact *= i;
            sum += fact;
            t /= 10;
        }

if (sum == num)
            System.out.println(num + " is a special number");
        else
            System.out.println(num + " is not a special number");
