Problem:
A/B Problem

Write a program which reads two integers a and b, and calculates the following values:

a ÷ b: d (in integer)

remainder of a ÷ b: r (in integer)

a ÷ b: f (in real number)

Input

Two integers a and b are given in a line.

Output

Print d, r and f separated by a space in a line. For f, the output should not contain an absolute error greater than 10-5.

Constraints

1 ≤ a, b ≤ 109

Sample Input 1

3 2

Sample Output 1

1 1 1.50000

Solution in JAVA (judge verdict: Wrong Answer)

import java.io.*;
public class Main {
	public static void main(String[] args){
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		try{
			String line = reader.readLine();
        	String[] num = line.split(" ", -1);
        	int a = Integer.parseInt(num[0]);
        	int b = Integer.parseInt(num[1]);
        	
        	int d = a / b;
        	int r = a % b;
        	float f = a / b;
        	
        	System.out.println(d + " " + r + " " + f);
        } catch (IOException e) {
          System.out.println(e);
        } catch (NumberFormatException e) {
          System.out.println("error");
        }
    }
}
