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: Accepted)

<?php
$b = array_fill(1,100,0);
while(fscanf(STDIN,'%d',$a)) {
    if(is_null($a)) {
        break;
    }
    $b[$a]++;
}
$max = max($b);
foreach($b as $c => $d) {
    if($max === $d) {
        echo $c . PHP_EOL;
    }
}
