2016huas暑假集训训练题 G-Who's in the Middle

题目链接：https://vjudge.net/contest/121192#problem/G

此题大意是给定一个数n 然后有n个数要求求出其中位数刚开始以为是按数学中的中位数当n为偶数时输出中间两位数之和再除以2 这题是只要先排序再输出第n/2个数即可

ac代码：

 1 import java.io.BufferedInputStream;
 2 import java.util.Arrays;
 3 import java.util.Scanner;
 4 
 5 public class Main {
 6     public static void main(String[] args) {
 7         Scanner s = new Scanner(new BufferedInputStream(System.in));
 8 
 9         while (s.hasNext()) {
10             int t = s.nextInt();
11             int a[] = new int[t];
12             for (int i = 0; i < t; i++)
13                 a[i] = s.nextInt();
14             Arrays.sort(a);  //数组排序
15              
16                 System.out.println(a[t / 2]);
17          
18         }
19         s.close();
20     }
21 }
