华为OJ 初级：输入n个整数，输出其中最小的k个

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

public class Main {
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int k = sc.nextInt();
int[] nums = new int
;
for(int i = 0; i < n; i++)
nums[i] = sc.nextInt();
sc.close();

Arrays.sort(nums);  //从小到大排序

for(int i = 0; i < k; i++){  //输出前k个数
if(i != k-1)
System.out.print(nums[i] + " ");
else
System.out.print(nums[i]); //最后一个数后面不加空格
}
}
}
