Watch

Write a program which reads an integer $S$ [second] and converts it to $h:m:s$ where $h$, $m$, $s$ denote hours, minutes (less than 60) and seconds (less than 60) respectively.

Input

An integer $S$ is given in a line.

Output

Print $h$, $m$ and $s$ separated by ':'. You do not need to put '0' for a value, which consists of a digit.

Constraints

$0 \leq S \leq 86400$

Solution in PHP (judge verdict: WA: Presentation Error)

<?php
$a = fgets(STDIN);
$h = floor($a / 3600);
//echo $h;
//echo "\n";

$hamari = $a % 3600;
//echo $hamari;
//echo "\n";
$m = floor($hamari / 60);
//echo $m;

//echo "\n";

$byou = $hamari % 60;
//echo $byou;

//echo "\n";

echo $h . ":" . $m . ":" .$byou;
/*
echo $h . ":" . $m . ":" $byou;
*/
?>
