Here's some Java code that checks if a number is a spy number:
class SpyNumber
{
void spy(int n)
{
int sum = 0;
int product = 1;
while (n > 0) {
int digit = n % 10;
sum += digit;
product *= digit;
n /= 10;
}
System.out.println("Sum: " + sum); // prints "Sum: 8"
System.out.println("Product: " + product); // prints "Product: 8"
if(sum==product)
{
System.out.println("SpyNumber");
}
else
{
System.out.println("Not aSpyNumber");
}
}
}
public class Main {
public static void main(String[] args) {
SpyNumber s=new SpyNumber();
s.spy(1124);
