Answer:
Check the explanation
Explanation:
Given a collection SS of subsets of a set X, an exact cover of X is a subcollection S∗S∗ of SS that satisfies two conditions:
- The intersection of any two distinct subsets in S∗S∗ is empty, i.e., the subsets in S∗S∗ are pairwise disjoint. In other words, each element in X. is contained in at most one subset in S∗S∗.
- The union of the subsets in S∗S∗ is X, i.e., the subsets in S∗S∗ cover X. In other words, each element in XX is contained in at least one subset in S∗S∗.
XX is the collection of letters on the refrigerator.
SS is the collection of words that your daughter knows that are made up of letters in X.
S∗S∗ is a subcollection of words from SS that exactly cover X.
