You are requested to perform image compression using Huffman coding. You have 6 possible symbols {a1, a2, a3, a4, a5, a6}. The probability for each symbol is [0.15, 0.25, 0.05, 0.05, 0.4, 0.1]. - Create the Huffman code for the following sequence: {a1, a3, a3, a4, a2, a5}. - Calculate the average word length of the 6 possible symbols. - Calculate the coding efficiency.
