The question is about information theory and the description is as below:

02 Make a sequence of {0,1 }128 by randomly typing 0 or 1 128 times and calculate its entropy in cases 1. Regard as a sequence of {0,1}128. 2. Regard as a sequence of {00,01,10,11}64. 3. Regard as a sequence of {0000,0001,0010,...,1111}32
