Why is this sentence correct? Why is the subject "students" or "they" omitted in "as did just a decade ago"? Can someone shed light on this peculiar construction and point to an online resource that gives a clear explanation? And what is the name for this kind of sentence construction?
"Only half as many students study computer science as did just a decade ago."
