How do dictionary-based compression algorithms work?
- By removing unnecessary whitespace
- By replacing repeated sequences with references to a dictionary
- By sorting the data before compression
- By using mathematical formulas to represent data
Dictionary-based compression algorithms work by identifying repeated sequences in the data and replacing them with references to a dictionary. This dictionary contains commonly occurring patterns or phrases, and their references help in reducing the overall size of the compressed data. This technique is efficient for repetitive data structures and patterns.
