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

46979

Sample Output 1

Solution in JAVA (judge verdict: Accepted)

import java.io.File;
import java.io.IOException;
import java.util.Scanner;

/*
 * メモ
 * Scanner:nextは空白か改行までの単語
 * String[][] c = new String[h][w];
 * TemplateMain,"template_input.txt"
 */

public class Main {
	
	public static void printlnYN(boolean b){
		if(b) System.out.println("Yes");
		else System.out.println("No");
	}

	public static void main(String[] args) throws IOException {
		
		//File file = new File("input.txt");
		//Scanner sc = new Scanner(file);
		
		Scanner sc = new Scanner(System.in);
		
    	int S = sc.nextInt();
    	
    	int h = S / 3600;
    	int m = (S % 3600) / 60;
    	int s = S % 60;
    	
    	System.out.println(h+":"+m+":"+s);
    	
	}
