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.

        public static void Main(string[] args)
        {
            int[] count = new int[101];
            int max;
            while (true)
            {
                string s = Console.ReadLine();
                if (string.IsNullOrEmpty(s)) break;

                int value = int.Parse(s);
                count[value]++;
            }
            max = count[0];
            for (int i = 0; i < 100; i++)
            {
                if (max < count[i]) max = count[i];
            }
            for (int i = 0; i < 100; i++)
            {
                if (max == count[i]) Console.WriteLine(i);
            }
        }
    }
}
