A) Great understanding of for loops as an iterative structure to sum up the elements of an array.
B) Again this problem was very similar to part A, but with the added complexity of an additional dimension. But you did everything correctly, demonstrating a solid understanding of how to traverse the dimensions of 2D Arrays.
C) Your code was great, building off previous methods you had coded, and comparing the different sums of each of the rows of the 2D Array. I like that you made a boolean variable to hold whether a 2D Array was diverse or not.
