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) {
  var t = input.split("¥n")[0];
  var h = Math.floor(t / 3600);
  var m = Math.floor(t % 3600 / 60);
  var s = Math.floor(t % 60);
  console.log([h, m, s].join(":"));
}

function debug() {
  var input = document.getElementById('id1').value;
  Main(input);
}

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