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 JAVA (judge verdict: Accepted)

import java.io.IOException;
import java.util.Scanner;

public class Main
{
    public static void main(String arg[])
    {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        int c = Integer.parseInt(a);

        int num = c / 3600;

        int k = c - num*3600;

        int i = k / 60;

        int h = k-i*60;

        System.out.println(num+":"+i+":"+h);
    }

}
