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: Accepted)

  using System;
  class a
  {
      static void Main()
      {
          int a=int.Parse(Console.ReadLine());
          int h=a/3600;
          int m=(a%3600)/60;
          int s=a%60;
          
          Console.WriteLine(h+":"+m+":"+s);
      }
  }
