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.io.*;

class Main {
	public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String secStr = br.readLine();
		int sec = Integer.parseInt(secStr);
		int[] hms = {0,0,0};
		for( int i = 0; i < 3 ; i++ ) {
			hms[i] = sec % 60;
			sec = sec / 60;
		}
		System.out.println(hms[2] + ":" + hms[1] + ":" + hms[0]);
	}
}
