  9. LZ77 and LZ78 - Wikipedia

    en.wikipedia.org/wiki/LZ77_and_LZ78

    Entry 1 is an 'A' (followed by "entry 0" – nothing) so AB is added to the output. Next 0B is added to the dictionary as the next entry, 3 {0,B} , and B (preceded by nothing) is added to the output. Finally a dictionary entry for 1$ is created and A$ is output resulting in A AB B A$ or AABBA removing the spaces and EOF marker.
