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 HelloWorld
{
    class Program
    {
        static void Main()
        {
            var counter = new int[100];
            string line;
            int max = -1;
            while ((line= Console.In.ReadLine())!=null)
            {
                ++counter[int.Parse(line) - 1];
            }

            foreach (var v in counter)
            {
                if (max < v)
                {
                    max = v;
                }
            }
            for (int i = 0; i < 100; ++i)
            {
                if (max == counter[i])
                {
                    Console.Out.WriteLine(i + 1);
                }
            }
        }
    }
}
