That is an excellent phrase.

I definitely agree that Selection sort should definitely not be described as O(n) to beginners. I was just pointing out a subtly. In the strange case where memory writes are much more expensive than reads or comparisons, it is correct to say the Selection sort takes O(n) time.

I'm not sure what conditions you have in mind, but in the selection sort, the comparisons are O(n^2), and the assignments are O(n).

If comparisons are a fixed, non-zero cost, and assignments are a fixed, non-zero cost, then the comparisons in your selection sort will always overwhelm the assignments, and I can tell you at exactly which input size.

Good one, but you probably meant Satyr (or Faun as Romans called it)

Centaurs are multifaceted and live rich, complex inner lives.
