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;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            int S;
            int h;
            int m;
            int s;

            S = int.Parse(System.Console.ReadLine());

            h = S / 3600;

            if(S % 3600 == 0)
            {
                m = 0;
                s = 0;


            }
            else
            {
                m = (S % 3600) / 60;

                s = m % 60;
            }

            System.Console.WriteLine("{0}, {1}, {2}", h, m, s);


        }
    }
}
