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

Let $G_1, G_2, G_3$, be valid generator matrices of dimensions $\mathbb F^{k_i imes n_i}$, all over the same field $\mathbb F$. Recall that ``valid'' means that for all $i$, $k_i \leq n_i$ and $ ext{rank}(G_i) = k_i$. True or false: Assuming $k_1 = k_2 + k_3$, the matrix $egin{pmatrix} G_1 &\vline &egin{matrix} G_2 &\vline &0\ \cline{1-3} 0 &\vline &G_3 \end{matrix} \end{pmatrix}$ is also a valid generator matrix.
