Comparing two arrays ignoring element order in Ruby

Question

I need to check whether two arrays contain the same data in any order. Using the imaginary compare method, I would like to do:

arr1 = [1,2,3,5,4         


        

Answer 1

You can actually implement this #compare method by monkey patching the Array class like this:

class Array
  def compare(other)
    sort == other.sort
  end
end

Keep in mind that monkey patching is rarely considered a good practice and you should be cautious when using it.

There's probably is a better way to do this, but that's what came to mind. Hope it helps!
