Question: A source output consists of five messages [m 1 , m 2 , m 3 , m 4 , m 5 ] with respective probabilities

A source output consists of five messages [m₁, m₂, m₃, m₄, m₅] with respective probabilities [0.35, 0.25, 0.2, 0.15, 0.05]. Determine the binary code words for the second-order source extension using the Shannon-Fano and Huffman coding techniques. Determine the efficiency of the resulting codes and comment on the results.
