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 … Meer weergeven 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. Meer weergeven 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 … Meer weergeven WebHuffman coding (also known as Huffman Encoding) is an algorithm for doing data compression, and it forms the basic idea behind file compression.
