(b) Consider four source codes listed in the table below: Symbol Code I Code II Code III Code IV S1 00 S2 10 01 01 01 S3 110 001 011 10 S4 1110 0010 110 110 S5 1111 0011 111 111 For each of these four source codes, identify whether it is a Prefix code or not and provide your reasoning. In case, you identify any of these codes to be a Prefix code, construct its decoding tree as well. (c) A source emits two messages m, and m2 with probabilities 0.75 and 0.25 respectively.
