Spy Number program
Write a program to accept a number and check and display whether it is a Spy Number or not.
A Number is spy number if the sum of its digits equals the product of its digits.
Example : consider the number 1124
Sum of the digits = 1 + 1 + 2 + 4
Product of the digits = 1 * 1 * 2 * 4
// ICSE 2017 Question Answer
import java.util.*;
public class SpyNumber
{
public static void main(String args[])
{
int no, pro, sum, digit;
pro = 1;
sum = 0;
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number to check spy number :");
no = sc.nextInt();
while(no != 0)
{
digit = no % 10;
pro = pro * digit;
sum = sum + digit;
no = no / 10;
}
if(sum == pro)
{
System.out.println("Spy Number");
}
else
{
System.out.println("Not Spy Number");
}
}
}
