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.io.*;

public class Main{
	public static void main(String[] args)throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		int toki,zikan,hun,byou;
		
		toki = Integer.parseInt(br.readLine());
		zikan = toki / 3600;
		hun = (toki % 3600)/60;
		byou = (toki % 3600) % 60;
		
		System.out.println(zikan+":"+hun+":"+byou);
	}
}
