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. one class english paper

"Webences in the character counts. The Huffman encoding scheme takes advantage of the disparity between frequencies and uses less storage for the frequently occurring characters at the expense of having to use more storage for each of the more rare characters. Huffman is an example of a variable-length encoding— " - Haufman code
