Languages may have features for dealing specifically with empty strings (those containing no characters). The task is to: Demonstrate how to a
Continue ReadingC++: Huffman Coding
Huffman encoding is a way to assign binary codes to symbols that reduces the overall number of bits used to encode a typical string of those symbols.
