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: WA: Presentation Error)

public class Main {
	public static void main(String[] args) {
		java.util.Scanner scn = new java.util.Scanner(System.in);
		int S = scn.nextInt();
		System.out.print(S/3600 + ":" + (S%3600)/60 + ":" + (S%3600)%60);
		scn.close();
	}
}
