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 open array class and define a method like this.

class Array
  def compare(comparate)
    to_set == comparate.to_set
  end
end

arr1.compare(arr2)
irb => true

OR use simply

arr1.to_set == arr2.to_set
irb => true
