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

$0 \leq S \leq 86400$

Sample Input 1

46979

Sample Output 1

13:2:59

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

<?php

function getTime($seconds, &$hour, &$minute, &$second){
    $leftSeconds=$seconds%86400;
    $hour=$leftSeconds/3600;
    $minute=($leftSeconds%3600)/60;
    $second=$leftSeconds%60;
}

$input=trim(fgets(STDIN));

$hour=0;
$minute=0;
$second=0;
getTime($input, $hour, $minute, $second);

echo floor($hour).":".floor($minute).":".floor($second)."\r\n";
?>
