MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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.*;

public class Main{
	public static void main(String[] args){
		//new Main().printHelloWorld();
		//System.out.println(new Main().ITP1_1_B(Integer.parseInt(new Scanner(System.in).next())));
		//new Main().ITP1_1_C();
		new Main().ITP1_1_D();
	}

	public void printHelloWorld(){
		System.out.println("Hello World");
	}

	public int ITP1_1_B(int x){
		return x*x*x;
	}

	public void ITP1_1_C(){
		Scanner scan = new Scanner(System.in);
		int a = scan.nextInt();
		int b = scan.nextInt();
		System.out.println(a*b + " " + 2*(a+b));
	}

	public void ITP1_1_D(){
		int seconds = new Scanner(System.in).nextInt();
		System.out.println(seconds/3600 + ":" + (seconds%3600)/60 + ":" + (seconds%3600)%60);
	}
}
