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: Wrong Answer)

<?php

$seconds = fgets(STDIN);

echo timeConversion($seconds);

function timeConversion($seconds){
    $hours = floor($seconds / 3600);
    $minutes = floor(($seconds / 60) % 60);
    $seconds = $seconds % 60;
    
    $hms = sprintf("%02d:%02d:%02d", $hours, $minutes, $seconds);
    
    return $hms;
}
