Huffiman codes (a) Construct a binary Huffman code for the following distribution on five symbols: 𝐩=(0.3,0.3,0.2,0.1,0.1). What is the average length of this code? (b) Construct a probability distribution 𝐩^' on five symbols for which the code that you constructed in part (a) has an average length (under 𝐩^' ) equal to its entropy H(𝐩^'). | Numerade

(20 pts.) Huffman Encoding. We use Huffman's algorithm to obtain an encoding of alphabet {a,b,c} with frequencies fa, fb, fc. In each of the following cases, either give an example of a specific set of frequencies fa, fb, fc that would yield the specified encoding or explain why the code cannot possibly be obtained. (a) {1,01,00} (b) {1,01,10} (c) {01,10,11}
