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 PHP (judge verdict: Wrong Answer)

<?php
$list = explode("\n",trim(fgets(STDIN)));
$count = array_count_values($list);
$max = max($count);
$num = array_keys($count,$max);
$getans = array();

foreach($num as $value){
  $getans[] = $value;
}
asort($getans);
$ans = implode("\n", $getans);
echo $ans;

//var_dump($num);
?>
