WebFor example, a Huffman tree cannot assign the codes 01 and 010 to two distinct characters. This prevents confusion when decompressing (e.g. X has code 01 and Y has code 0101, the input 0101 could be interpreted as XX or Y). The set of all codes generated by a Huffman tree contains prefixes for every possible binary input. WebStep by Step example of Huffman Encoding.

WebNov 2, 2024 · Huffman's algorithm is a particular algorithm which is guaranteed to produce a minimum redundancy code. Huffman's algorithm makes some arbitrary choices along the way, and consequently there are many codes which it can produce (for example, we could change the meaning of $0$ and $1$). Each such code is called a Huffman code for $\mu$.
