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

$0 \leq S \leq 86400$

namespace ITP1_1D
{
    class Program
    {
        static void Main(string[] args)
        {
            int Seconds = int.Parse(Console.ReadLine());
            int Minutes = Seconds / 60;
            Seconds = Seconds % 60;
            int Hours = Minutes / 60;
            Minutes = Minutes % 60;
            Console.WriteLine(Hours.ToString("D2") + ":"
                + Minutes.ToString("D2") + ":"
                + Seconds.ToString("D2"));
            //TimeSpan convertTime = new TimeSpan(0, 0, sec);
            //Console.WriteLine(convertTime.Hours.ToString("D2") + ":" 
            //    + convertTime.Minutes.ToString("D2") + ":" 
            //    + convertTime.Seconds.ToString("D2")); 
        }
