Below are three different codes for the symbols a, b, c and d. If the encoding could be a Huffman encoding, then display the Huffman tree and any probability of the symbols matching it. If the encoding cannot be a Huffman encoding, justify it. a: 0, b: 11, c: 101, d: 100 a: 01, b: 0, c: 110, d: 111 a: 00, b: 10, c: 01, d: 11
