Problem:
Mode Value

Your task is to write a program which reads a sequence of integers and prints mode values of the sequence.
The mode value is the element which occurs most frequently.

Input

A sequence of integers ai (1 ≤ ai ≤ 100). The number of integers is less than or equals to 100.

Output

Print the mode values. If there are several mode values, print them in ascending order.

Sample Input

5
6
3
5
8
7
5
3
9
7
3
4

Output for the Sample Input

3
5

For example, 3 and 5 respectively occur three times, 7 occurs two times, and others occur only one. So, the mode values are 3 and 5.

Solution in JAVA (judge verdict: Wrong Answer)



import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.HashMap;

public class Main {
    public static void main(String args[]){
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        try{
            String line;
            HashMap<Integer, Integer> hm = new HashMap<Integer,Integer>();
            
            while((line=br.readLine())!=null){
                if(line.equals(""))break;
                String[] splited = line.split(" ");
                int m = Integer.parseInt(splited[0]);
                if(hm.containsKey(m))hm.put(m, hm.get(m)+1);
                else hm.put(m,1);
            }
            ArrayList<Integer> maxes = new ArrayList<Integer>();
            int max=0;
            for(int key:hm.keySet()){
                if(hm.get(key)<max)continue;
                if(hm.get(key)>max){max=hm.get(key);maxes.clear();maxes.add(key);}
                maxes.add(key);                    
            }
            for(int i:maxes)System.out.println(i);
        }catch(Exception e){e.printStackTrace();}
    }
