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;
class Main {

	public static void main(String[] args) {
		Scanner in=new Scanner(System.in);
		int S=in.nextInt();
		int h=S/3600;
		int h1=S%3600;
		int m=h1/60;
		int m1=h1%60;
		System.out.println(h+":"+m+":"+m1);
	}
	
}
