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[]) {
	Scanner s = new Scanner(System.in);
	int a =s.nextInt();
	int a1 = a/3600,a2 = a%3600;
	int b1 = a2/60,c1 = a2%60;
	System.out.println(a1+":"+b1+":"+c1);
	s.close();
}
