Huffman 壓縮/解壓算法的ANSI C實現
This archive contains a simple and readable ANSI C implementation of Huffman
coding and decoding. This implementation is not intended to be the best,
fastest, smallest, or any other performance related adjective.

This book is the product of a twenty-year resarch project at Rice University
to develop fundamental compiler technologies for vector and parallel
computer systems. The effort was by Randy Allen and Ken Kennedy with the help of David Kuck and Michael Wolfe.

This is a simple algorithm that downloads trading data from yahoo database. It is basically a large scale application of sqq.m which was originally submitted by Michael Boldin, link at acknowledgements.
Some of the functionalities of the package:
- User defined ticker list.
- Function for downloading most recent SP500 composition in ticker list.
- Control for bad data (e.g. a certain percentage of prices missing).
- Choice of frequency of data (e.g. weekly prices).
- Choice of starting and ending data.
- Function for saving the whole data in a pre-formatted excel file together with a full reports on missing data.
