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
while (!feof(STDIN)) {
	$input[] = trim(fgets(STDIN));
}

foreach ($input as $value){
	if (!isset($cntMode[$value])){
		$cntMode[$value] = 1;
	} else {
		$cntMode[$value] ++;
	}
}
$min=min($cntMode);
$nums = array_keys($cntMode, $min);
sort($nums);
$result = implode("\n",$nums);
print ($result);
?>
