Detailed explanation-1: -Which of the following is true about Huffman Coding. a)Huffman coding may become lossy in some casesb)Huffman Codes may not be optimal lossless codes in some casesc)In Huffman coding, no code is prefix of any other code. d)All of the aboveCorrect answer is option ‘C’.
Detailed explanation-2: -Huffman coding is a lossless data compression algorithm. The idea is to assign variable-length codes to input characters, lengths of the assigned codes are based on the frequencies of corresponding characters. The most frequent character gets the smallest code and the least frequent character gets the largest code.
Detailed explanation-3: -In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A.
Detailed explanation-4: -Huffman codes are of variable-length, and prefix-free (no code is prefix of any other). Any prefix-free binary code can be visualized as a binary tree with the encoded characters stored at the leaves.
Detailed explanation-5: -1. Which of the following algorithms is the best approach for solving Huffman codes? Explanation: Greedy algorithm is the best approach for solving the Huffman codes problem since it greedily searches for an optimal solution.
