The code table is wrong. Huffman odes are supposed to be prefix free . This is neccessary in order to decode them afterwards without ambiguities.
Not only is the code table wrong, the lengths of the codes are also wrong. If you have two one-bit codes, you have already used up all of the code space, and can have no other codes. What you have shown is not only not a Huffman code and not a prefix code -- it is in fact not a code at all.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
