a few weeks ago in comp sci

We have recently started working on references and parameters, but I am still stuck on the tic tac toe lab refs and params are fairly simple with only a few rules that need to be followed such as whether or not a method changes or doesn't change the value of a string or number, but once you have that down, it is fairly simple. The syntax is a tiny bit confusing like always, but that is really the only way to make this concept hard, so it is understandable. I have to think for a while and draw a simple chart for some of these problems, but I can chug on through most of them so for now I am doing well.
