You are right, I was off.

On another note: I absolutely do not understand why we substitute the international mathematical symbol for cardinality (|A|) with variables we have to explain.

Computer science has a math background, so we all know set theory. At least I also learned using cardinality with Big O notation in university. But for some reason industry prefers to use variables here.

I'm not sure my math classes ever actually mentioned that particular notation. I agree it's more elegant to formalize the analysis, but it's not particularly elegant on the webpage -- the kerning feels off.
