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.Scanner;

class Main{

    static Scanner scan;

    public static void main(String[] args) {
        scan = new Scanner(System.in);

        int n = scan.nextInt();

        int h = n / 3600;
        int s = n % 60;
        int m = (n - h*3600) / 60;

        System.out.printf("%d:%d:%d\n", h, m, s);
    }
}
