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 C# (judge verdict: Wrong Answer)

using System;
using System.Collections.Generic;
using System.Linq;


namespace Library
{
    public class Miscelleneous
    {
        public static void print(object j){Console.WriteLine(j.ToString());}
        
        public static void Main(){
            string s;
            int[] I=new int[100];
            int k;
            while(true){
                s=Console.ReadLine();
                if(string.IsNullOrEmpty(s))break;
                k=int.Parse(s);
                I[k-1]++;
            }
            
            int M=I.Max();
            
            for(int i=0;i<100;i++)
                if(I[i]==M)print(i);
        }
    }
}
