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 {
	class Program {
		public static void Main() {
			int input = int.Parse(Console.ReadLine());
			int h = input / 60 / 60;
			int m = (input / 60) % 60;
			int s = input % 60;

			Console.WriteLine(h + ":" + m + ":" + s);
		}
	}
