Dude, what kind of exam is this? I thought we were supposed to be learning about streams, not counting methods! This is making my head spin.

Hmm, I think count() and reduce() are the reduction methods, but I'm not 100% sure. I'll have to double-check the docs on that.

I'm not sure about this. Can someone explain why count() and collect() are used for reduction?
