Hi I just had a couple of questions about the mid-semester exam It was said in the workshop that there are topics in the practice exam from previous years, do questions on sort apply for this, I know they relate to the pre-requisites for the unit, but just wondering if that's something we should briefly brush up on? If we get a question like one: "Write a dynamic programming algorithm for calculating the nth term of a fibonacci series", do we just write the answer in pseudo-code? Thanks
