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;
	class Program
	{
		public static void Main(string[] args)
		{
			
			int seconds=int.Parse(Console.ReadLine());
			
			int h=seconds/3600;
			int m=(seconds%3600)/60;
			int s=(seconds%3600)%60;
			
			Console.WriteLine(h+":"+m+":"+s);
			
			
			
		}
	}
