I think it’s $<, but I’m not entirely confident. It seems to fit the description of updating elements directly.

I think the answer might be $elemMatch, but I'm not completely sure. It sounds familiar from our practice questions.

I remember something about updating arrays, but I can't recall if $slice is the right operator for this.
