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

$0 \leq S \leq 86400$

Sample Input 1

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int s = Integer.parseInt(in.next());
		int hour = s / 60 / 60;
		int minuit = s / 60 % 60;
		int second = s - hour * 60 * 60 - minuit * 60;
		
		System.out.println(hour + ":" + minuit + ":" + second);
	}
}
