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.*;
import java.io.*;

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