A multiset is an unordered collection where elements can appear multiple times. We will represent a multiset of Char elements as a function from Char to Int: the function returns 0 for any Char argument that is not in the multiset, and the (positive) number of times it appears otherwise: type Multiset = Char => Int What should replace ??? so that the following function computes the underlying set of the m multiset, formed from its distinct elements? For example, the underlying set of the multiset M = {'a', 'a', 'c', 'd', 'd'} is S = {'a', 'c', 'd'}. type Set = Char => Boolean def multisetToSet(m: Multiset): Set = ???
A. (x: Int) => m(x) > 0
B. x => m(x) > 0
C. (x: Char) => m(x)
D. (x: Char) => m(x) == 0
E. m(x) > 0
F. m(x)
