		for (first = number; first >= 10; first = first / 10);
		return first + last;
	}


	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Ente number: ");
		int number = keyBoard.nextInt();
		System.out.println("The sum of the first and Last digis: " + sumFirstAndLastDigits(number));
		keyBoard.close();
	}
