O n

Oct 17, 2010 · While mathematically true, O(n) notation is used loosely almost all the time, even by those that do know better. In particular, it is considered deceptive to use a higher O-class than strictly necessary; so no practitioner will ever refer to an O(n) algorithm as being O(n²), although any algorithm that is in O(n) is also (by definition) in O(n²)
