Huffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree. Huffman Coding prevents any ambiguity in the decoding process using the concept of prefix code ie. a code … See more Suppose the string below is to be sent over a network. Each character occupies 8 bits. There are a total of 15 characters in the above string. Thus, a total of 8 * 15 = 120bits are required to send this string. Using the Huffman … See more For decoding the code, we can take the code and traverse through the tree to find the character. Let 101 is to be decoded, we can traverse from the root as in the figure below. See more The time complexity for encoding each unique character based on its frequency is O(nlog n). Extracting minimum frequency from the priority queue takes place 2*(n-1) times and its complexity is O(log n). Thus the overall … See more WebHuffman Coding is a famous Greedy Algorithm.

WebSep 8, 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 ...
