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.math.BigDecimal;
import java.util.Scanner;

public class Main{

	public static void main(String[] args) {
		// TODO ?????????????????????????????????????????????
		Scanner sc = new Scanner(System.in);
		String line = sc.nextLine();
		String[] x = line.split(" ");
		int a = Integer.parseInt(x[0]);
		int b = Integer.parseInt(x[1]);
		double fa = Integer.parseInt(x[0]);
		double fb = Integer.parseInt(x[1]);
		System.out.print(a / b + " ");
		System.out.print(a % b + " ");
		double f = fa / fb;
		BigDecimal B = new BigDecimal(f);
		BigDecimal F = B.setScale(9, BigDecimal.ROUND_HALF_UP);
		System.out.println(F);

	}
