    int a = sc.nextInt();

    System.out.println(function1(a));

    }

    public static int function1(int a) {

        int b = 0;

        if (a >= 10) {

            b = 3 * a - 11;

            } else if (a >= 1) {

            b = 2 * a - 1;

            } else {

            b = a;

            }
