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: Accepted)

<?php

// 0 <= S < 86400
fscanf(STDIN, '%d', $S);
$h = $S / (60 * 60);
$m = $S % (60 * 60) / 60;
$s = $S % (60 * 60) % 60;
printf('%d:%d:%d%s', $h, $m, $s, PHP_EOL);
