(b.) Huffman code is a way to encode information using variable-length binary strings to represent symbols depending on the frequency of each individual letter. Specifically, letters that appear more frequently can be encoded into strings of shorter lengths, while rarer letters can be turned into longer binary strings. On average, Huffman code is a more efficient way to encode a message as the number of bits in the output string will be shorter than if a fixed-length code was used....

For this assignment, you will write a program to work with Huffman encoding. Huffman code is an optimal prefix code, which means no code is the prefix of another code. Most of the code is included. You will need to extend the code to complete three additional methods. In particular, code to actually build the Huffman tree is provided. It uses a data file containing the frequency of occurrence of characters. You will write the following three methods in the...
