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: Accepted)

using System;

namespace P0028_ModeValue
{
    class Program
    {
        static void Main(string[] args)
        {
            var map = new int[100]; 

            while (true)
            {
                var line = Console.ReadLine();
                if (line == null) break;

                map[int.Parse(line)-1]++;
            }
            
            int max = 0;

            foreach (var m in map)
            {
                if(max < m) max = m;
            }

            for (int i = 0; i < 100; i++)
            {
                if (max == map[i]) Console.WriteLine(i+1);
            }

        }
    }
}
