Using the Huffman Coding technique, we can compress the string to a smaller size. Huffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree. Hu...
Huffman coding is an algorithm for compressing data with the aim of reducing its size without losing any of the details. This algorithm was developed by David Huffman. Huffman coding is typically useful for the case where data that we want to compress has frequently occurring characters in it....
In this paper we proposed the Lossless method of image compression and decompression using a simple coding technique called Huffman coding. This technique is simple in implementation and utilizes less memory.Sanjay Kumar Gupta
Huffman code is a type of optimal prefix code that is commonly used for lossless data compression. The algorithm has been developed by David A. Huffman. The technique works by creating a binary tree of nodes. Nodes count depends on the number of symbols.
16.2 -Elements of the greedy strategy - same as 16.1 16.3 -Huffman codes - I'd say read the problem and the algorithm, but that's enough. I've seen interview questions where the answer is Huffman coding (but the question will come up in a 'disguised form', so it won't be obvious...
