WebThe encoding algorithm should be capable of accepting successive events from different probability distributions. Arithmetic coding has this capability. Moreover, the code acts directly on the probabilities, and can adapt “on the fly” to changing statistics. WebHuffman Encoding can be used for finding solution to the given problem statement. Developed by David Huffman in 1951, this technique is the basis for all data compression and encoding schemes It is a famous algorithm used for lossless data encoding It follows a Greedy approach, since it deals with generating minimum length prefix-free binary codes
WebApr 3, 2024 · Huffman Coding is a lossless data compression algorithm where each character in the data is assigned a variable length prefix code. The least frequent character gets the largest code and the most frequent one gets the smallest code. Encoding the data using this technique is very easy and efficient.
