Good job with the do ... loop. Can you think of a way to generalize the algorithm so that it works for n bits?

Good job with using the math operator **. Can you think of a faster way to perform this without having to use the ** operation? Your code currently requires recalculating 2 to the power of n (number of bits) at every iteration.

Nice work! Think about the comments and questions that your code review buddy shared with you, and discuss them further with your buddy. |
