Determining whether one array contains the contents of another array in ruby

Question

In ruby, how do I test that one array not only has the elements of another array, but contain them in that particular order?

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


        

Answer 1

I would like to consider continuous sequence of elements from other array in container array and present this:-- code is inspired from the Sawa's code

class Array
  def contain? other
   arr = self & other
   (arr.eql? other ) && ((self.index(arr.last) - self.index(arr.first)).eql?(other.size - 1))
  end
end

Result:--

correct_combination = [1, 2, 3, 4, 5]
[1, 5, 8, 2, 3, 4, 5].contain?(correct_combination) # => false
[8, 10, 1, 2, 3, 4, 5, 9].contain?(correct_combination) # => true
[1, 8, 2, 3, 4, 5].contain?(correct_combination) # => false
