creation of the Shannon-Fano coding in the old exam 2020

Question

in the old exam 2020  task 1.f . I wonder if there is an error in the solution, because in the calculation you said (when dividing the quantities please assign the 0 to the half that contains the symbols with the higher probabilities. probabilities) but you have given 0 to two with 0.49 instead of 0.51 which on the other hand equalled 1  Translated with DeepL.com (free version)

Answer 1

Yes, that is true. The solution had been generated with the former version of the teaching tool which did not follow the remark given in the problem description. Since the remark in the problem description makes sense to define a canonical solution, I have updated the teaching tool accordingly and have also fixed the solution in the exam paper.

Thanks for pointing this out!
