What is the primary mechanism by which the LZ77 algorithm achieves data compression?
By replacing repeated data sequences with references to earlier occurrences within a sliding window
By assigning shorter codes to more frequent symbols based on their probabilities
By removing all redundant data without storing any references to previous data
