Ruby基于传递给方法的可变数量的参数创建数组

Question

我有一个方法，我想传递一些参数，然后根据传入的参数创建一些数组。

def method(*args)
  number_of_arrays = args.count
  for i in 1..number_of_args
    # create arrays
  end
  args.map do |arg|
      # do something and add to an array
  end
  # I should now have a number of different arrays based on how many arguments are passed in
  # do something with those arrays
end

任何指导？

Answer 1

def method(*args)
  arrays = Array.new(args.count) { [] }

  args.each_with_index do |arg, index|
      arrays[index] << # add some form of the arg to each array
  end
end
