33:01 I think in knn(the simplest version of it) as a multiclass classification because if we have 2(class 1), 2(class 2) and 1(class3) with a given K=5 so we cannot decide wheter the point belongs to class 1 or class 2. I think we must use some techniques like One-versus-all or One-versus-one to make it suitable to be used with multiclass classification.
