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 C# (judge verdict: Accepted)

using System;
using System.Linq;

class Program
{
	static void Main(string[] args)
	{
		var input = int.Parse(Console.ReadLine());
		var hour = input / 3600;
		input %= 3600;

		var minute = input / 60;
		input %= 60;

		System.Console.WriteLine(hour + ":" + minute + ":" + input);

	}
