Recursion for Mathematical Expressions should definitely be rated Hard. The official CG solution is over 300 lines long. Tower of Hanoi is probably appropriately rated, as an averaged difficulty based on whether or not you know the process for solving the real Tower of Hanoi puzzle or not. Unfortunately, I do not. If you give me the real Tower of Hanoi puzzle I do not know how to solve it, aside from trial and error. I skipped both of these two tasks. 😁
