Web1 okt. 2016 · Huffman encoding is used in lossless data compression and is a good example for educational applications that target any operating system and can be easily implemented in Java and C#. This paper presents the implementation of Huffman algorithm on multiple frameworks (Oracle Java, OpenJDK Java, .NET Framework, Mono … WebSolution. Since Huffman coding needs to use 1 bit per symbol at least, to encode the input, the Huffman codewords are 1 bit per symbol on average: This gives a gap of 1 − 0.72 = 0.28 bit. The performance of the Huffman encoding algorithm is, therefore, 0.28/1 = 28% worse than optimal in this case. temporary employee staffing agency contract
