输入n个整数，输出其中最小的k个

import java.util.Scanner;
import java.util.Arrays;


public class Main{

    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        while(sc.hasNext()){
            int n = sc.nextInt();
            int num = sc.nextInt();
            int[] a = new int[n];
            for(int i = 0; i < n; i++){
                a[i] = sc.nextInt();
            }
            Arrays.sort(a);
             for(int i = 0; i < num; i++){
                System.out.print(a[i] + " ");
            }
            System.out.println();
