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 Ruby (judge verdict: Accepted)

def read_input
  gets.split(" ").map(&:to_i)
end

class ABProblem
  def initialize(a, b)
    @a, @b = a, b
  end

  def div
    @a / @b
  end

  def mod
    @a % @b
  end

  def div_float
    sprintf("%.5f", @a.to_f / @b.to_f)
  end
end

a, b = read_input
p = ABProblem.new(a, b)
puts [p.div, p.mod, p.div_float].join(" ")
