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 scanner = new Scanner (System.in);
int S = scanner.nextInt();
int h = S/3600;
int x = S%3600;
int m = x/60;
int s = x%60;
System.out.println(h + ":" + m + ":" + s);
}
}
