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: Accepted)

import java.io.*;
import java.util.Scanner;

public class Main {
	public static String watch(int s) {
		String res = "" + s / 3600;
		s = s % 3600;
		res = res + ":" + s / 60 + ":" + s % 60;
		return res;
	}

	public static void main (String[] args) {
		Scanner sc = new Scanner(System.in);
        int s = sc.nextInt();
        System.out.println(watch(s));
	}
