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 myclass
{
    public static void Main()
    {
        int S = Int32.Parse(Console.ReadLine());
        int s = S % 60;
        int m = ((S - s) % 3600) / 60;
            ;
        int h = (S - s - m) / 3600;
        Console.WriteLine(h + ":" + m + ":" + s);
    }
}
