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;
using System.Text;
      
      
namespace ConsoleApplication13
{
    class Program
    {
        static void Main(string[] args)
        {
            string line;
            List<int> b = new List<int>();
            List<int> c = new List<int>();
            List<int> d = new List<int>();
            for(int i=0;i<100;i++)b.Add(0);
            while((line=Console.ReadLine())!=null)
            {
                int a = int.Parse(line);
                Console.WriteLine(a);
                b[a-1]++;
            }
                for(int e=0;e<b.Count;e++)
                    c.Add(b[e]);
                b.Sort();
                b.Reverse();
                for(int f=0;f<b.Count;f++)
                {
                    if(c[f]==b[0])
                    d.Add(f+1);
                 }
                 for(int r=0;r<d.Count;r++)Console.WriteLine(d[r]);
    
    }
  }
