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

46979

Sample Output 1

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {

		Scanner scanner = new Scanner(System.in);

		int sec = scanner.nextInt();

		// ??????
		int h = sec / 3600;

		// ???
		int m = (sec - (3600 * h)) / 60;

		// ?§?
		int s = sec - (3600 * h) - (60 * m);

		System.out.println(h + ":" + m + ":" + s);
	}
