import java.util.Scanner;

public class ArrayRotation {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int n = scan.nextInt();
        int r = scan.nextInt();
        int[] a = new int[n];
        int[] b = new int[n];
        for (int i = 0; i < n; i++) {
            a[i] = scan.nextInt();
        }
        scan.close();

        if (r % n == 0) {
            printOriginalArray(a);
        } else {
            r = r % n;
            for (int i = 0; i < n; i++) {
                b[i] = a[(i + r) < n ? (i + r) : ((i + r) - n)];
                System.out.print(b[i] + " ");
            }
        }
    }

    private static void printOriginalArray(int[] a) {
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i] + " ");
        }
    }
