Web8 sep. 2024 · Theory of Huffman Coding. Huffman coding is based on the frequency with which each character in the file appears and the number of characters in a data structure with a frequency of 0. The Huffman encoding for a typical text file saves about 40% of the size of the original data. We know that a file is stored on a computer as binary code, and ...
