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 s = (new Scanner(System.in)).nextInt();
		int hour = s/3600;
		int min = (s%3600)/60;
		int sec = (s%3600)%60;
		
		System.out.printf("%d:%d:%d\n", hour, min, sec);
	}
