Huffman

A simple library set for Huffman's Coding algorithm

This is a hobby project initiated by Ashkan Taravati and Behzad Chizari alongside with Dr. Jahanshahi's 'Design and Analysis of Algorithms' Course. The major classes of this library are as follows:

-HuffmanTree:

A Binary tree that stores Huffman Elements in a Generic List.

-HuffmanElement (Implements IComparable):

A class declaration for objects holding values and frequencies for each character found in input string. It also represents Huffman Tree Nodes. and

-HuffmanEncoder:

The main body for the encoder; Gets a string, finds frequencies of each character, instatiates Huffman Elements for each character, builds a Huffman tree, generates a dictionary according to each element and generates a string of bits by replacing each character in the input string with their Huffman code.

-HuffmanDecoder:

The main body for the decoder; Reads a .bin file parsing it as a binary string and parses a json file converting it to a dictionary. It will then replace binary Huffman codes in the binary string with their corresponding characters, rebuilding the original string.

-OutputStream:

A class for File IO Procedures.

-JSONWriter:

A class featuring required methods for generating a string containing json object out of the Generic Dictionary used in HuffmanEncoder.
