Algorithm for decompression

Decompression algorithms reverse the compression process by reconstructing the original data from its compressed form. Typically, they analyze the compressed data to identify patterns or symbols that were shortened or replaced during compression. Using a predefined set of rules or a dictionary, the algorithm maps these codes back to their original data, gradually rebuilding the complete file or message. This process ensures that the decompressed output matches the original input exactly, allowing for efficient storage and transmission while preserving data integrity.
