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

Solution in JavaScript (judge verdict: Accepted)

function Main(input) {
    input = input.split("\n");
    for (i=0; i < input.length-1; i++) {
        var S = parseInt(input[i], 10)
        var h = Math.floor(S / 60 /60)
        var m = Math.floor(S / 60 % 60)
        var s = Math.floor(S % 60)
        var hh = String(h)
        var mm = String(m)
        var ss = String(s)
        var c = ":"
        console.log('%s', hh + ":" + mm + ":" + ss);
    }
}

Main(require("fs").readFileSync("/dev/stdin", "utf8"));
