Yes. First off, you can arbitrarily assign 0 and 1, or 1 and 0, to each pair of branches of the tree to get equally valid codes.

Is Huffman code unique?

Example. We give an example of the result of Huffman coding for a code with five characters and given weights. ... For any code that is biunique, meaning that the code is uniquely decodeable, the sum of the probability budgets across all symbols is always less than or equal to one.

Can there be multiple Huffman codes?

In a true Huffman code, no code sequence can ever also be the prefix of another. ... As a simplified example, if you had just four different values, then the code lengths could be (2, 2, 2, 2) or (1, 2, 3, 3), each with the byte lengths in any order, for example (2, 3, 1, 3).
