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

46979

Sample Output 1

13:2:59

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main{

	public static void main(String[] args) {

		Scanner sc = new Scanner(System.in);
		int time = sc.nextInt();

		// 時間
		int hour = time / 60 / 60;
		// 分
		int minutes = time / 60 % 60;
		// 秒
		int sec = time % 60;

		System.out.println(hour + ":" + minutes + ":" + sec);

	}
