re: Are these lists equal? VIEW POST

FULL DISCUSSION
 

A great example of how one can sacrifice memory for CPU time! However, what is the point of counting if by the original condition "You can assume that there's no duplicate item in any of the lists". We might as well use sets here for simplicity.

 

Yeah, a set would work perfectly well. That's the kind of realization I wanted from the post. I'd rather write about the general use case to have readers drill down to more optimal solutions.
