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 Assuming that elements of multisets are only lowercase letters of the English alpha- bet, what does the secret function compute? def diff(a: Multiset, b: Multiset): Multiset = \t x => Math.abs(a(x) - b(x)) def secret(a: Multiset, b: Multiset) = \t (’a’ to ’z’).map(x => diff(a, b)(x)).sum == 0
A. Checks if b is a subset of a
B. Checks if a and b are disjoint
