Huffman Coding is a technique of compressing data to reduce its size without losing any of the details. It was first developed by David Huffman. Huffman Coding is generally useful to compress the data in which there are frequently occurring characters. Meer weergeven 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 … 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 Web14 jun. 2024 · Huffman coding is an algorithm to generate the binary code based on the frequencies of corresponding characters in the input string.
