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.Scanner;

public class Main {
public static void main(String args[]) {
	int h,m,s,x;
	Scanner a = new Scanner(System.in);
	x = a.nextInt();
	
	h = x / 3600;
	m = x % 3600 / 60;
	s = x % 3600 % 60;
	System.out.println(h +":"+ m + ":" + s);
}
