import java.io.*;
class GFG
{
// function to find if number
// is special or not
static void specialNumber(int n)
{
// Checking whether entered
// number is 2 digit or not
if(n < 10 || n > 99)
System.out.println("Invalid Input! " +
"Number should have " +
"2 digits only");
else
{
// Finding the first digit
int first = n / 10;
// Finding the last digit
int last = n % 10;
// Finding the sum
// of the digits
int sum = first + last;
// Finding the product
// of the digits
int pro = first * last;
if((sum + pro) == n)
{
System.out.println(n + " is a Special" +
" Two-Digit Number");
}
else
{
System.out.println(n +" is Not a Special" +
" Two-Digit Number");
}
}
