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:
1 import java.io.BufferedOutputStream; 2 import java.io.BufferedReader; 3 import java.io.InputStreamReader; 4 import java.io.PrintWriter; 5 import java.util.Arrays; 6 7 8 public class Main { 9 public static void main(String[] args) throws Exception{ 10 // TODO Auto-generated method stub 11 BufferedReader bf = new BufferedReader(new InputStreamReader(System.in)); 12 int N = Integer.parseInt(bf.readLine()); 13 int[] ar = new int[N]; 14 for(int i = 0;i < N;i++){ 15 ar[i] = Integer.parseInt(bf.readLine());; 16 } 17 Arrays.sort(ar); 18 19 PrintWriter pw = new PrintWriter(new BufferedOutputStream(System.out)); 20 for(int i = 0;i < N;i++) 21 pw.println(ar[i]); 22 pw.flush(); 23 } 24 25 }
