Actually I don't think the homework required a split answer. But there is a tradition of providing a somewhat obscure answer to questions that look like homework. If OP asks questions, well and good. If not then they probably can't simply regurgitate the "answers" they have been given and expect to get good marks for it.

Perl is Huffman encoded by design.
