Decompression

As explained in Classic Computer Science Problems in Swift: Essential techniques for practicing programmers

Decompression is the process of reversing a compressed representation to recover the original data.

Decompression reverses a compressed representation to recover the original data. It trades execution time for reduced storage or transmission size, making sense when space matters more than immediate execution. section 1.2

Compressed gene

Calling decompress() on CompressedGene(original: "ATGAATGCC") reconstructs the original gene string.

How Classic Computer Science Problems in Swift: Essential techniques for practicing programmers covers it

How deep it goes
Implements bit-pair decoding in Swift and preserves length, without developing general compression formats or algorithms.
Examples
Uses a two-bit DNA encoding and reconstructs the string ATGAATGCC.
What it assumes
Assumes basic Swift and binary familiarity while recalling how bits represent values.
What you can do after
Builds a Swift decompressor that reconstructs nucleotide strings from a CFMutableBitVector.
How it connects
Connects decompression with compression, binary representation, bit vectors, and storage efficiency.
