题解 | 输入n个整数，输出其中最小的k个

import java.util.*;

// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int k = in.nextInt();


        int[] ints = new int[n];
        for (int i = 0; i < n; i++) {
            ints[i] = in.nextInt();
        }
        int[] array = Arrays.stream(ints).sorted().toArray();

        for (int j = 0; j < k; j++) {
            System.out.print(array[j]);
            if (j != k-1) {
                System.out.print(" ");
            }
        }
    }
