Question 25

Write a program to accept a number and check and display whether it is a spy number or not. (A number is spy if the sum of its digits equal the product of its digits.)
Example : Consider the number 1124,
Sum of the digits = 1 + 1 + 2 + 4 = 8
Product of the digits = 1 x 1 x 2 x 4 = 8.

Answer
import java.util.Scanner;

public class KboatSpyNumber
{
    public static void main(String args[]) {
        
        Scanner in = new Scanner(System.in);
        
        System.out.print("Enter Number: ");
        int num = in.nextInt();
        
        int digit, sum = 0;
        int orgNum = num;
        int prod = 1;
        
        while (num > 0) {
            digit = num % 10;
            
            sum += digit;
            prod *= digit;
            num /= 10;
        }
        
        if (sum == prod)
            System.out.println(orgNum + " is Spy Number");
        else
            System.out.println(orgNum + " is not Spy Number");
        
    }
}
