Spy Number – SchoolCodeHub

Spy Number is a number whose sum of digits and product of digits are equal.

Example 1: 22. 2+2 = 2*2 = 4. Hence it is a Spy Number.

Example 2: 44. 4+4 ≠ 4*4. Here the sum of digits is not equal to the product of digits. Hence it is not a Spy Number.

        Scanner sc=new Scanner(System.in);
        System.out.print("Enter a number: ");
        n=sc.nextInt();
