Hi Jay,

I have submitted some errors I think I have found in your book. Are you planning to respond to the submissions? Especially the technical submissions.

Thanks, Neil! These are all great catches. I’ve just fixed all of them and the corrections will be included in the next release.

Hi Jay!

From Chap. 2 (Oh Yes! Big O Notation):

Because there will always be some amount of data in which the tides turn, and O( N) takes more steps from that point until infinity, O(N) is considered to be, on the whole, less efficient than O(N).

Believe the latter should be O(1). Thanks!

Yes, thanks! I’ve already fixed that one - it will be in the next version.

Page 65. The array after the first shift should be [2,4,7,1,3]. You have [4,8,2,3].
