Answer 1

Answer:

For each value of k, there are N complex multiplications, and N − 1 complex additions. There are N values of k, so the total number of complex operations is N · N + N(N − 1) = 2N2 − N ≡ O(N2). Complex multiplies require 4 real multiplies and 2 real additions, whereas complex additions require just 2 real additions.
