4.21. Consider a memoryless source with S={,,,} and P()=0.5, P()=0.3,P()=0.1,P()=0.1. Calculate the average wurdlength of the corresponding arithmetic code for S2. [You do not need to find the codewords.] Compare this value with the entropy of the source. 4.22. If the source is as in the previous exercise, find the codewurds for: (i) in the code for S2; and (ii) in the code for S3
