The function should take the following parameter: tokens: A list of clean tokens from which to build the vocabulary. The function build_vocab should return a set of unique tokens, which will be our vocabulary. Execute the build_vocab function using cleaned_train_text to construct a set of unique words, which will serve as the vocabulary for the N-gram model. Store the result in a variable named vocab, ensuring that the placeholder is not included in the vocabulary ps.: Trying to remove the placeholder from the train text will produce an error since this placeholder only exists in the test text.
