huffman
huffman
An implementation of Huffman algorithm in Crystal for learning purposes (using 0 and 1 in a String array).
To compress real files a new implementation using BitArray should be required.
A real usecase of Huffman coding is Zstandard and Huff0 used in kernel compresion
Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.

Usage
require "huffman"
h = Huffman.new # Using ASCII table
p h.encode("Hello World") # => 1111100111011011001001100100110001000111001010010110001011010001100100111010
h = Huffman.new("Hello World") # Using "Hello World"
p h.encode("Hello World") # => 01000101000001111011101110000101
p h.decode("01000101000001111011101110000101") # => Hello World
