In the handout (lecture 21, page 2 of 2), the critical path length for mergesort with plain merge (not parallel merge) was given as T_inf(n) = T_inf(n/2) + Theta(1) = Theta(n).
Shouldn't this be T_inf(n) = T_inf(n/2) + Theta(n) = Theta(n)?

Checked the video. The notes were wrong. The video was right with
T_inf(n) = T_inf(n/2) + Theta(n) = Theta(n).
Otherwise the result would have been Theta(log n).
