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: WA: Presentation Error)

import java.io.*;

public class Main{
    public static void main(String args[]){
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        try{
            String line = reader.readLine();
            int n = Integer.parseInt(line);
            int h,m,s;
            h = n / 3600;
            m = (n - h*3600) / 60;
            s = (n - h*3600 - m*60);
            System.out.printf("%d:%d:%d", h, m, s);
        } catch(IOException e){
            System.out.println(e);
        }
    }
