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

$0 \leq S \leq 86400$

Solution in C# (judge verdict: Wrong Answer)

using System;

namespace AOJ
{
    class Program
    {
        static void Main(string[] args)
        {

            string read = Console.ReadLine();
            int time = int.Parse(read);

            int hour, min, sec;

            hour = time / 360;
            time = hour * 360;
            min = time / 60;
            time = min * 60;
            sec = time;


            Console.WriteLine(hour+":"+min+":"+sec);
        }
    }
}
