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 Aizu
{
    public class OnlineJuedge
    {
        public static void Main()
        {
            var array = new int [101];
            var max = 0;
            for(string input; (input = Console.ReadLine()) != null;) {
                max = Math.Max(++array[int.Parse(input)], max);
            }
            for(int i = 1; i <= 100; ++i){
                if(max == array[i]) {
                    Console.WriteLine(i);
                }
            }
        }
    }
}
