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.Linq;
using System.Text;
using System.Threading.Tasks;

namespace _0028
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] countNum = new int[101];
            List<int> modes = new List<int>();
            string inputNum;
            while ((inputNum = Console.ReadLine()) != null)
            {
                countNum[int.Parse(inputNum)] += 1;
            }
            int numModes = countNum.Max();
            for (int i = 1; i < 101; ++i)
            {
                if (numModes == countNum[i])
                    modes.Add(i);
            }
            modes.Sort();
            foreach (int mode in modes)
                Console.WriteLine(mode);
        }
    }
