SPY Number ICSE Computer Science

A number is called SPY number if the sum of the digits equals the number of the digits.

Example:

1021 is a SPY number

1+0+2+1 = 4

Number of digits = 4

Let's start the code of determining if a number is SPY or not.

Below is the code for determing if a number is SPY.

import java.util.Scanner;

class Spy

{

    public static void main(String[]args)

    {

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter a number");

        int num = sc.nextInt();

        int sum = 0,temp = num, count = 0;

        while(temp>0)

        {

            int digit=temp%10;

            sum = sum+digit;

            count++;

            temp/=10;

        }

        if(sum == count)

        {

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

        }

        else

        {

            System.out.println(num+" is not a Spy number");

        }

    }

}

Now, write this program and test it with various numbers and increase your knowledge.

Happy Coding.......
