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

$0 \leq S \leq 86400$

Solution in JAVA (judge verdict: Accepted)

import java.util.*;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws Exception {
        // Your code here!
        Scanner sc = new Scanner(System.in);
        int h = 0;
        int m = 0;
        int s = 0;
        
        int a = sc.nextInt();
        
        while(a>=3600){
            a -= 3600;
            h++;
        }
        
        while(a>=60){
            a -= 60;
            m++;
        }
        
        s = a;
        
        
        System.out.println(h+":"+m+":"+s);
    }
