In 2018 I did a 400-level CS class that was an introduction to computer audio. One of the assignments was to implement a fast fourier transform. After class I went to the cafeteria and hacked one out in like an hour or 2. A week or so later as the assignment was nearing due, apparently many, if not most of the students complained the assignment was too hard because... they seemingly just didn't know how to write code?

They ended up changing the assignment to where you could just find an implementation of a FFT online and write about it or something.

That's not even getting into the students who copy-pasted Wikipedia straight into their papers in that same class.
