Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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

46979

Sample Output 1

Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

class Main {

	public static void main(String[] args) {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		
		try {
			String input = br.readLine();
			int s;

			s = Integer.parseInt(input);
			
			if (!(s >= 0 && s <= 86400)) {
				throw new IllegalArgumentException();
			}
			
			int hh = s / 3600;
			int mm = (s % 3600) / 60;
			int ss = s % 60;
			
			System.out.println(hh + ":" + mm + ":" + ss);
		
		} catch(NumberFormatException e) {
			e.printStackTrace();
		} catch(IllegalArgumentException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
