: The text contains repeating sequences like "Christine", "Watson", and versioning numbers ("2.0c"). ChristineWatson-2.0c.p.1-Win-compressed.zip

: A method where the original data can be perfectly reconstructed from the compressed data. : A "rule of thumb" or a problem-solving

: The mapping of symbols to the original patterns that must be stored alongside the compressed text to decode it. or ★) to these repeated chunks.

: A "rule of thumb" or a problem-solving approach (like looking for the longest repeated patterns first) to find a "good enough" compression ratio, even if it's not the absolute best possible one.

For a step-by-step walkthrough of how to solve this specific puzzle, you can view this Lossless Compression Tutorial which covers Lesson 9 in the CS Principles curriculum.

: You assign symbols (like ☀, ☁, or ★) to these repeated chunks.
