Hi!

Speaking of learning concepts, if I wanted to use Maps without Stream, what are the steps I would use for that? Specifically, from the half-dozen websites I researched, but it seems like I will have to manually place strings into the maps; is this correct?

Will operation time be O(n + q + hash_constant), then?

This is one of my first posts; sorry if this is a stupid question/formatted badly.

Thanks in advance.
