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;

namespace ITP1_1_D
{
  class Program
  {
    static void Main(string[] args)
    {
      int line = int.Parse(Console.ReadLine());
      int hour = line / (60 * 60);
      int minuts = (line - hour * 3600) / 60;
      int second = line - (minuts * 60 + hour * 3600);


      Console.WriteLine("{0}:{1}:{2}", hour, minuts, second);
    }
  }
}
