输入描述:

输入多行，先输入随机整数的个数，再输入相应个数的整数

输出描述:

返回多行，处理后的结果

输入例子1:

11102040326740208930040015

输出例子1:

10152032406789300400 分别使用HashSet与TreeSet实现

import java.util.ArrayList;import java.util.Collections;import java.util.HashSet;import java.util.Iterator;import java.util.Scanner;public class M2 {	public static void main(String[] args) {		Scanner scanner=new Scanner(System.in);		while (scanner.hasNext()) {					HashSet
     
       aList=new HashSet
      
       ();				int i=scanner.nextInt();		for (int j=0; j< i; j++) {							aList.add(scanner.nextInt());																					}		Iterator iterator=aList.iterator();		ArrayList
       
         n =new ArrayList
        
         ();		for (int j = 0; j < aList.size(); j++) {			n.add((Integer) iterator.next());		}		Collections.sort(n);		for (int m = 0; m < aList.size(); m++) {			System.out.println(n.get(m));		}		}	}}
        
       
      
     

 while(sc.hasNext())不只一个输入

import java.util.Scanner;import java.util.TreeSet;public class M3 {	public static void main(String[] args) {		Scanner scanner=new Scanner(System.in);		while (scanner.hasNext()) {						TreeSet
     
       aList=new TreeSet
      
       ();					int i=scanner.nextInt();			for (int j=0; j< i; j++) {								aList.add(scanner.nextInt());																						}						for (Integer m : aList) {				System.out.println(m);			}		}	}}
