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.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main{
	public static void main(String[] args) throws IOException{
		InputStreamReader is = new InputStreamReader(System.in);
		BufferedReader br = new BufferedReader(is);

		String str = br.readLine();

		calc(str);
	}

	public static void calc(String str){
		int num = Integer.parseInt(str);
		int s,m,h;

		h = num/3600;
		m = (num-3600*h)/60;
		s = num - 3600*h -60*m;

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