public static void main(String[] args) {
System.out.println("Welcome to HiLo!");
System.out.println("Difficulty");

System.out.println("2. Medium (1-100)");
System.out.println("3. Hard (1-1000)");
Scanner sc = new Scanner(System.in);
int choice = sc.nextInt();

if (choice == 1) {

} else if (choice == 3) {
playGame(1000);
}
}

public static void playGame(int maxNumber) {
Scanner sc = new Scanner(System.in);
int number = (int) (Math.random() * maxNumber) + 1;
System.out.println("Guess a number between 1 - " + maxNumber);
int guess = 0;
int attempts = 0;

while (guess != number) {

giveResponse(guess, number, attempts++);
}
}

public static void giveResponse(int guess, int answer, int attempts) {

}

if (guess < answer) {
System.out.println("Too low, try again!");
} else {
