Watch

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.

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.

Constraints

$0 \leq S \leq 86400$

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main{
    public static void main(String[]args){
	Scanner sc = new Scanner(System.in);
        double a=sc.nextInt();
        double b=2*a*Math.PI;
        double c=a*a*Math.PI;
	System.out.printf("%f %f",b,c);
       
    }
}
