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: Wrong Answer)

import java.util.*;

class Main {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int n = scan.nextInt();
        int h = 0;
        int m = 0;
        int s = 0;

        for(int i=1; i < 2000; i++) {
            s = n - 60;
            if(s < 60) break;
        }
        
        int s_left = n - s;
        int m_left = s_left/60;
        
        for(int j=1; j < 2000; j++) {
            m = m_left - 60;
            if (m < 60) break;
        }

        h = (m_left - m)/60;

        System.out.println(h+":"+m+":"+s);
    }
}
