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.

Constraints

* $0 \leq S \leq 86400$

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.

Example

Input

46979


Output

13:2:59
import java.util.*;

public class Main{
	public static void main(String[] args){
		int S = new Scanner(System.in).nextInt();
		int h = S / (60 * 60);
		int m = S % (60 * 60) / 60;
		int s = (S % (60 * 60)) % 60;
		System.out.println(h + ":" + m + ":" + s);
	}
