Webbboundaries. Huffman coding creates such a code. Huffman algorithm is not very different from Shannon - Fano algorithm. Both the algorithms employ a variable bit probabilistic coding method. The two algorithms significantly differ in the manner in which the binary tree is built. Huffman uses bottom-up approach and Shanon-Fano uses Top-down … 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 Coding technique, we can compress the string to a smaller size. Huffman coding first … Visa mer 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. Visa mer The time complexity for encoding each unique character based on its frequency is O(nlog n).
