import java.util.Scanner;

public class Inbetween {

    public static void main (String args[]) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter two integers: ");
        int n1 = in.nextInt();
        int n2 = in.nextInt();
        if (n1 > n2 + 1) {
            for (int i = n1-1; i > n2; i--) {
                System.out.print(i + " ");
            }
            System.out.println();
        } else if (n1 + 1 < n2) {
            for (int i = n1+1; i < n2; i++) {
                System.out.print(i + " ");
            }
            System.out.println();
        } else {
            System.out.println("There are no integers between " + n1 + " and " + n2);
        }
    }
