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 Test
{
    static void Main()
    {
        int S = Convert.ToInt32(Console.ReadLine());
        int hh = S / 3600;
        int mm = (S - (hh * 3600)) / 60;
        int ss = S - hh * 3600 - mm * 60;

        Console.WriteLine("{0}:{1}:{2}", hh, mm, ss);
    }
}
