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