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.util.*;
class Main{
	static Scanner s = new Scanner(System.in);
	public static void main(String[] args) {
		final String d = ":";
		int	i = Integer.parseInt(s.next());

		System.out.print  (i/3600);
		i%=3600;
		System.out.print  (d+i/60);
		i%=60;
		System.out.println(d+i);
	}
}
