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

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main{
	
	int S;
	int hour;
	int min;
	int seco;
	
	public void solve(){
		Scanner sc = new Scanner(System.in);
		S =sc.nextInt();
		
		hour = S / 3600;
		min = (S - hour*3600) / 60;
		seco= (S - hour*3600) - (min*60);
		
		System.out.println(hour+":"+min+":"+seco);
		
	}
	
	public static void main(String[]args){
		Main obj = new Main();
		obj.solve();
	}
