【CodeChef】Turbo Sort

题目链接：Turbo Sort

用java自带O(NlogN)的排序就可以，java要特别注意输入输出。输入用BufferedReader，输出用printWriter。printWriter的速度比System.out快很多，参考StackOverflow。

代码：

 import java.io.BufferedOutputStream;
 import java.io.BufferedReader;
 import java.io.InputStreamReader;
 import java.io.PrintWriter;
 import java.util.Arrays;

 public class Main {
     public static void main(String[] args) throws Exception{
         // TODO Auto-generated method stub
         BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
         int N = Integer.parseInt(bf.readLine());
         int[] ar = new int[N];
         for(int i = 0;i < N;i++){
             ar[i] = Integer.parseInt(bf.readLine());;
         }
         Arrays.sort(ar);

         PrintWriter pw = new PrintWriter(new BufferedOutputStream(System.out));
         for(int i = 0;i < N;i++)
             pw.println(ar[i]);
         pw.flush();
     }

 }
