Input and Sliding Window

This gives the current encoding/decoding status with the search buffer and look-ahead buffer. It also indicates the length of the match if there is a match.

Instructions

It has some instructions to explain about how the algorithm works.

Encoded Triples

It lists the compression output: the encoded triples.

LZ78

Input String

It lists the input string and marks the character that is being processed.

Output String

It lists the compression output.
