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") ????????§???????????????

    var data = parseInt(input.split("\n"))
    console.log(Math.floor(data/3600) + ":" + Math.floor((data%3600)/60) + ":" + data%60);
}


// Don't edit this line!
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
