Hi. I was wondering if the midsem test will be covering any material about unit testing since it was only covered briefly in Lecture 12.

You can get either to work, but given that the isPrime method has no reason to depend on any object state, static makes the most sense.

Hello So, for lab 3 exercise 1, I wanted to add user attempts based on their input range, as I have previously done this as a python exercise. With python it's a bit simpler, like so min num guesses round(math.log2(B - A 1)). I have had a look a...
