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: WA: Presentation Error)

using System;

class Program
{
    static void Main()
    {
        int S = int.Parse(Console.ReadLine());

		int h = S / 3600;
        int m = S % 3600 / 60;
        int s = S % 60;

        Console.Write("{0}:{1}:{2}", h, m, s);
    }
}
