Finite integer sets A=[-3, -2, -1, 1, 2, 3] and B=[]; repeated elements count once. Ordered candidates=[-1, -2, -3]. For each c, answer whether c∈A and c∉B; a candidate outside A cannot be an obstruction.
View answer and explanation
[Yes, Yes, Yes]
Require membership in A before excluding membership in B; shared elements and outside-A elements are not counterexamples. The exact result, retaining the requested order, is [Yes, Yes, Yes].
