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.Scanner;

class Main {
 
	public static void main( String args[] ) {
		Scanner scan = new Scanner(System.in);
	    long x, jikan, hun, byou;
	    x = scan.nextLong();
	    jikan = x / 3600;
	    hun = (x - (jikan * 3600)) / 60;
	    byou = x - (jikan * 3600 + hun * 60);
	    
	    
	    System.out.println(jikan + ":" + hun + ":" + byou);
	    
	    //System.out.println(jikan);
	    //System.out.println(hun);
	    //System.out.println(byou);
    }
