import java.util.Scanner;

public class Timechange {

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

int hour,minute,second;

second = input.nextInt();

hour = second/3600;

minute = (second – hour*3600)/60;

second = second-hour*300-minute*60;

System.out.println(” hour is “+hour+” minute is “+minute+” second is “+second);

}

}
