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 JavaScript (judge verdict: Wrong Answer)

process.stdin.resume();
process.stdin.setEncoding('utf8');

process.stdin.on('data', function (chunk) {
var line = chunk.split(' ');
var hour_sec = 60*60;
var minitu_sec = 60;
var s = Number(line[0]);

var h = s / hour_sec;
var m = (s % hour_sec) / minitu_sec;
var sec = s % hour_sec %  minitu_sec;

console.log(h+' '+m+' '+s);
    
});
