 Asymmetric numeral systems

Asymmetric Numeral Systems (ANS) is a coding method used in data compression, designed to effectively compress sequences of symbols while providing a fast decoding process. ANS combines concepts from arithmetic coding and Huffman coding, but offers various benefits over these traditional methods. ### Key Features of ANS: 1. **Efficiency**: ANS is particularly efficient in both time and space. It can achieve high compression ratios while ensuring fast encoding and decoding speeds.
