: The original long string is rewritten using these symbols, significantly reducing the total character count (the "compressed" size). Key Concepts in the Lesson ChristineWatson-2.0c.p.1-Win-compressed.zip
: 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
: 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.
