题解 输入整型数组和排序标识，对其元素按照升序或降序进行排序

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner fzhinput = new Scanner(System.in);
        int num = fzhinput.nextInt();
        int sz[] = new int [num];
        fzhinput.nextLine();
        for (int i = 0; i < num; i++) {
            sz[i] = fzhinput.nextInt();
        }
        fzhinput.nextLine();
        int pd = fzhinput.nextInt();
        Arrays.sort(sz);
        if (pd == 0) {
            for (int i = 0; i < num; i++) {
                System.out.print(sz[i] + " ");
            }
        } else if (pd == 1) {

            for (int i = num - 1; i >= 0; i--) {
                System.out.print(sz[i] + " ");
            }
        }
    }
}
