Text File Compression And Uncompress Using Huffman Coding

WebHuffman invented a greedy algorithm that creates an optimal prefix code called a Huffman Code. The algorithm builds the tree T analogous to the optimal code in a bottom-up manner. It starts with a set of C leaves (C is the number of characters) and performs C - 1 'merging' operations to create the final tree. Web5 aug. 2024 · Huffman Coding.
