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: Wrong Answer)

using System;

namespace Watch
{

	class Watch
	{
		static void Main()
		{
			int h;
			int m;
			int s;
			
			s = int.Parse(Console.ReadLine());
			
			h = s / (60 * 60);
			s -= (h * 60 * 60);
			
			m = s / 60;
			s -= (m * 60);

			Console.WriteLine(h + ":" + m + ":" + s + "\r");
			
			Console.WriteLine("Prease any key to exit.");
            Console.ReadLine();
		}
	}
