find the unique elements in two arrays in Ruby

def unique_elements(array1, array2)
  array1 | array2
end

This code uses the ”|” operator to combine the two arrays and return only the elements that are unique to each array. The first line of the code defines a method called “unique_elements” that takes two arguments—the two arrays we want to combine. The second line uses the ”|” operator, which acts as a “union” operator, returning the unique elements of both arrays. The result of the operation is a new array with only the unique elements from both arrays, without duplicates.
