I'm not sure if I just misunderstand the directions or if it is a legitimate error that is_power_of_two(25) returns FALSE. The way I understand it, the directions indicate that they would like it to return TRUE being that 5**2 is 25.

If I am right in my assumption, would you still put this as a medium or would it be hard? I haven't applied yet, but I'm working on it.

25 is not a power of 2; it is a square number. The powers of 2 are: 2^1 (2), 2^2 (4), 2^3 (8), 2^4(16), and so forth.

Thank you for the clarification. I figured I was over l was too close to the issue.
