Question

I have an array like :
input2 = ["Other", "Y", "X", "Z", "Description"]

I want to take off the "Y", "X", "Z", "Description" and store them in a variable but keep them in that order.
Example :
input2 = ["Z", "X", "Y", "Other", "Description"] we should have :

input3 = ["Other"]
some_variable = ["Z", "X", "Y", "Description"]

Thanks for help.

Answer 1

def take_it_off(arr, values)
  without = []
  ordered_values = []
  arr.each do |val|
    if values.include? val
      ordered_values << val
    else
      without << val
    end
  end

  return without, ordered_values
end

So you can do

irb> values = "Y", "X", "Z", "Description"
=> ["Y", "X", "Z", "Description"]

irb> arr = ["Z", "X", "Y", "Other", "Description"]
=> ["Z", "X", "Y", "Other", "Description"]

irb> take_it_off(arr, values)
=> [["Other"], ["Z", "X", "Y", "Description"]]
