no_widows.exs

defmodule Text do
  def widows(some_str) do
    title_list = some_str |> String.split(" ") |> Enum.map(&String.capitalize/1)
    title_str  = Enum.join(title_list, " ")
    if Enum.count(title_list) > 2 do
      String.replace(title_str, ~r/\s+\S*$/, "&nbsp;" <> List.last(title_list))
    else
      title_str
    end
  end
end

IO.inspect Text.widows "hello there world"

# "Hello There&nbsp;World"
