The cryptic Ruby function takes an array as an argument and returns an array of the items that occur more than once in the original array.

It does this using the inject method specifying an empty Hash as the accumulator. It iterates over each item in the array by referencing the item index position, and passes the resulting item into the accumulator. This builds up a hash of key/value pairs with the key being the item from the initial collection and the value representing the number of times the item appears in the array. It then uses the reject method on the resulting hash and iterates over the hash returning a new array containing the items in self for which the given block is false.

Using idiomatic Ruby a cleaner way to write this function would be:

def show_duplicates(collection)
  collection.select { |element| collection.count(element) > 1 }.uniq
end

def flatten_clone(array, level = -1, result = [])
  array.each do |element|
    if element.is_a?(Array) && level != 0
      flatten_clone element, level - 1, result
    else
      result << element
    end
  end
  result
end
