Same question here.
I guess it might be to keep the code in more neat fashion, but it looks really weird.

Very effiecient!

And, the lift can be equipped with sensors to detect the number of people.

Sure, it "can be". But in the real world have you ever seen such a thing? I think my current rule is closer to reality. The lift stops because someone called it... doors open... but sorry no more room... doors close.. lift continues.

I don't think this is a reasonable rule. It makes tests cases wired. And, the lift can be equipped with sensors to detect the number of people.

whoa

This taught me about initializing in the capture clause. Thanks

Because the argument type was changed from const std::string & to just a std::string, the string will be passed by value, i.e., copied, and thus any changes are to the copy, not the original.

lvoe me some interavls

"When called, the Lift will stop at a floor even if it is full, although unless somebody gets off nobody else can get on!"

Ah, right, makes sense now. Without that it would be way more efficient... but usually an elevator does not really know if there is still capacity.

Nice brevity

Next level mastery of bit manipulation. Bravo!

Should generate a wider range of random tests

Raised as an issue.

:D

haha
