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.*;
public class Main {
    public static void main(String[] args)throws IOException {
        BufferedReader br =new BufferedReader(new InputStreamReader(System.in));
        String line=br.readLine();
        int time = Integer.parseInt(line);
        int sec=0,min=0,hour=0;
        
        if (time>=3600) {
            hour=time/3600;
            time=time%3600;
            min=time/60;
            sec=time%60;
            System.out.println(hour+":"+min+":"+sec);
        }
        else if (time>=60) {
            min=time/60;
            sec=time%60;
            System.out.println(hour+":"+min+":"+sec);
        }
        else{
