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

Solution in JavaScript (judge verdict: Accepted)

const input = require('fs').readFileSync('/dev/stdin', 'utf8');
let hour = Math.floor(input / 3600);
let minite = Math.floor((input - 3600 * hour) / 60);
let sec = (input - 3600 * hour) - (minite * 60);
console.log(hour + ":" + minite + ":" + sec);
