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;

public class p0028{
	p0028 ()
	{
		string str;
		int[] a = new int[101];
		int n = 0;
		
		while ((str=Console.ReadLine())!= null)
			++a [int.Parse (str)];
		
		for (int i = 0; i < 101; ++i)
			n = Math.Max (n, a [i]);
		
		for (int i = 0; i < 101; ++i)
			if (a [i] == n)
				Console.WriteLine ("{0}", i);
	}
	
	public static int Main (string[] args)
	{
		new p0028 ();
		return 0;
	}
}
