Java實現

import java.util.*;

public class Main {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        //flag爲1則n爲奇數，爲0則n爲偶數
        int flag = n&1;
        int max,min;
        double mid;
        int[] arr = new int[n];
        for(int i=0;i<n;i++){
            arr[i] = in.nextInt();
        }
        if (arr[0]<=arr[n-1]){

        }
        //偶數個
