22. Introduction to Recursive Solutions and Huffman Coding

22. Introduction to Recursive Solutions and Huffman Coding

The chapter discusses Huffman coding, a greedy algorithm used for optimal binary encoding based on frequency analysis. It explains how to construct a minimum cost encoding tree by recursively combining the lowest frequency characters until an optimal tree is achieved. The chapter also touches on the historical context of information theory and how Huffman's algorithm improved upon earlier methods.
