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.util.Scanner;
import java.lang.Math;

public class Main {

	public static void main(String[] args) {

		Scanner sc = new Scanner(System.in);

		int r = sc.nextInt();

		sc.close();

		double pi = Math.PI;

		double area = r * r * pi;
		double cir = 2 * pi * r;

		System.out.println(String.format("%.6f", area) + " " + String.format("%.6f", cir));

	}
