Consider a source that emits six symbols x1 x2 ) with probabilities 0.3. 0.25, 0.2, 0.1, 0.1 and 0.05 respectively. (i) construct a shannon-fano code for this source. [12 marks] (ii) calculate the average codeword length. [4 marks] (iii) calculate the entropy of the source. [4 marks] (iv) calculate the coding efficiency of the source.

Kirk found a local community college with a two-year program and he is comparing the cost with that of an out-of-state two-year school. what is the expected total cost for one year at the local community college if kirk lives at home? what is the expected total cost for one year at the out-of-state school if kirk lives on campus?

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
