This is the compression system and includes the BPS pre-process followed by Huffman coding (see program comments for Huffman credits).

Alicetest.txt - is the old contest text input file
tiebreak.txt - frequency tiebreaker file

Not ready to release the decompress yet. It works accurately yielding
lossless compression however optimization to speed up the run time
is in progress.

here is the Bigram Prediction System Restore. It uses the Huffman output from compression, decompresses Huffman codes, then restores a lossless original file. See credits for Huffman decode and Quicksort. It runs in about 4 minutes.
