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 Program
 {
     static void Main(string[] args)
     {
         double result;
         double sec,min,hour;
         string nyuryoku;
         nyuryoku = Console.ReadLine();
         result = Double.Parse(nyuryoku);
         sec = result % 60;
         min = (result - sec) / 60;
         result = min % 60;
         hour = (min - result) / 60;
         min = result;

         Console.WriteLine("{0}:{1}:{2}",hour,min,sec);
     }
 }
