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

46979

Sample Output 1

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
import java.util.concurrent.*;

public class Main{
	public static void main(String[] args){
		long s,sec,min,hour;
		Scanner in = new Scanner(System.in);
		
		s = in.nextLong();
		
		hour = TimeUnit.SECONDS.toHours(s);
		min = TimeUnit.SECONDS.toMinutes(s) - hour*60;
		sec = TimeUnit.SECONDS.toSeconds(s) - hour*3600 - min*60;
		
		System.out.println(hour+":"+min+":"+sec);
	}
