What is a prefix code?
Think about how this affects decoding.
Why is variable-length encoding advantageous?
Consider fixed-length limitations.
What is a prefix code?
Think of how this relates to decoding letters.
True or False: Huffman coding uses fixed-length codes for all characters.
Consider how Huffman coding operates.
Create a Huffman tree for the characters A, B, C with frequencies 0.5, 0.3, and 0.2 respectively. Explain your process.
Draw the tree as you combine the nodes.
Given a message consisting of the letters {A, B, C} with frequencies {0.6, 0.2, 0.2}, hypothesize how the encoded messages would look like.
Think about how Huffman coding balances to place common letters higher in the tree.
