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;

public class Main {
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int S = sc.nextInt();
        int h = 0;
        int m = 0;
        int s = 0;
        s = S%60;
        if(S/60<60){
            m = S/60;
            h = 0;
        }else{
            h = S/3600;
            m = S/60%60;
        }
        System.out.println(h+":"+m+":"+s);
        sc.close();
    }
