有没有大佬，贴上自己的代码，观摩一下啊

import java.util.Scanner;

public class SingerMain {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

int m = sc.nextInt();

int[] a = new int[n];

int[] aa = new int[m];

for (int i = 0; i < m; i++) {

aa[i] = sc.nextInt();

}

for (int j = 0; j < m; j++) {

a[aa[j] - 1] = 1;

}

double[] len = new double[n];

for (int i = 0; i < n; i++) {

for (int j = 0; j < n; j++) {

if (a[j] == 1) {

len[i] += Math.abs(j - i);

}

}

}

double min = n;

int index = 0;

for (int k = 0; k < n; k++) {

if (len[k] / m > 1.0) {

if (a[k] != 1) {

if (len[k] / m < min) {

index = k + 1;

min = Math.min(min, len[k] / m);

}

}

}

}

System.out.println(index);

}

}
