This weekend, curiosity got the better of me, so I decided to dive deep and implement Huffman coding from scratch.</p> <h2> What you'll learn: </h2> <ul> <li>🌳 How Huffman trees work (with visual examples)</li> <li>📊 Why Huffman is perfect for text/code compression </li> <li>🔍 Step-by-step walkthrough of the "Mississippi" example</li> <li>⚡ How to achieve ~50% compression on typical text files</li> </ul> <h2> Why Huffman? </h2> <p>Unlike Run Length Encoding (great for images), Huffman coding shines with the kind of files we work with daily - source code, JSON, XML, plain text. It assigns shorter bit sequences to frequent characters and longer ones to rare characters.</p> <p>The best part? It's lossless - your original file is perfectly restored after decompression.</p> <h2> What we'll build: </h2> <p>A complete compression/decompression system including:</p> <ul> <li>Frequency analysis</li> <li>Huffman tree construction </li> <li>Bit-level file operations</li> <li>Compact tree serialization</li> </ul> <p>Ready to see how "Mississippi" becomes just 3 bytes? Let's dive in! 👇</p> <p><a href="https://miakoring.de/blog/huffman" rel="noopener noreferrer">Continue reading on my blog →</a></p> <p><em>P.S. The CLI tool is called "Kompressor" after my vacuum-packed cat plushie that never fully "decompressed" 😸</em></p> computerscience algorithms swift beginners
