基础练习 数列排序

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

public class Main{


    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int num = sc.nextInt();
        int[] arr = new int[num];

        for (int i = 0; i < num; i++) {
            arr[i] = sc.nextInt();
        }
                //使用Arrays类进行快速排序
        Arrays.sort(arr);
        for (int i : arr) {
            System.out.print(i+" ");
        }
        System.out.println();

        
    }
}
