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;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace mondai0028
{
	class Program
	{
		static void Main(string[] args)
		{
			int[]	num	= new int[ 101 ];

			while( true ) {
				var	s	= Console.ReadLine();
				if( s == null ) {
					break;
				}
				num[ int.Parse( s ) ]++;
			}
			
			int	max	= 0;
			for( int i = 1; i <= 100; i++ ) {
				if( num[ i ] > max ) {
					max	= num[ i ];
				}
			}

			for( int i = 1; i <= 100; i++ ) {
				if( num[ i ] == max ) {
					Console.WriteLine( i );
				}
			}
		}
	}
