To confirm, one of the outputs would be 200, 200, 200, 100? Because subset implies sets, and every value in a set is there an indefinite number of times -- set {200, 100} is the same as set {200, 200, 200, 100} so from any set you can "withdraw" any element multiple times.
Likewise, if we find any duplicates in the array, they should be treated the same as if they had only appeared once, correct?
