Pretty pathetic but I only read 4 pages today and I left confused. Seems that one exercise had a copy method that when I made a change to an element in the copied array, it had no impact on the first array. However, in the next exercise, it did have an impact. I read it over and over but could not quite figure out the difference between what was done in the first exercise vs. the second.
Well, I will go deeper into this tomorrow and maybe I will understand it a little better.
