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

$0 \leq S \leq 86400$

import java.util.*;                                                                                  

public class Main {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        String line = sc.nextLine();
        double S = Integer.parseInt(line);

        double h = Math.floor(S / 3600);
        double H = S % 3600;
        double m = Math.floor(H / 60);
        double s = H % 60; 

        int ho = (int)h;
        int mo = (int)m;
        int so = (int)s;

        System.out.println(ho + ":" + mo + ":" + so);
    }
