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.Threading.Tasks;

namespace ITP1_1_D
{
    class Program
    {
        static void Main(string[] args)
        {
            //秒単位の時間Sを、h:m:sの形式へ変換して出力

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

            int h = S / 3600;           //1時間は3600秒なので、全体の秒数を3600で割った答えがh
            int m = S % 3600 / 60;      //(S/3600 の余り)/60
            int s = S % 3600 % 60;

            Console.WriteLine("{0}:{1}:{2}", h, m, s);  //フォーマット出力
                                                        //{0}の部分にh,{1}の部分にm

            Console.ReadKey();
        }
    }
