            System.out.print("Enter input number: ");
            int inputNumber = scanner.nextInt();
 
            if (inputNumber < 0) {
                System.out.printf("Input number %d is a negative number", inputNumber);
            } else if (inputNumber > 0) {
                System.out.printf("Input number %d is a positive number", inputNumber);
            } else {
                System.out.println("Input number is zero");
