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.util.Scanner;

class Main
{
	public static void main(String[] args)
	{
		int s;
		int m = 0;
		int h = 0;
		
		Scanner scan = new Scanner(System.in);
		s = scan.nextInt();
		
		for(; s >= 60 ;){
			s -= 60;
			m++;       }
			
		for(; m >= 60 ;){
			m -= 60;
			h++;       }
		
		System.out.println(h+":"+m+":"+s);
	}
}
