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
public class Main{
  public static void main(String[] args){
    int input= new java.util.Scanner(System.in).nextInt();
    int h=input/3600;
    int m=(input-h*3600)/60;
    int s=input-h*3600-m*60;
    System.out.println(h+":"+m+":"+s);
}
}
