Given the following data structure: enum IntSet: \t case Empty \t case NonEmpty(x: Int, l: IntSet, r: IntSet) And the following lemmas, holding for all x: Int, xs: List[Int], ys: List[Int], l: IntSet and r: IntSet: (SizeNil) nil.size === 0 (SizeCons) (x :: xs).size === xs.size + 1 (ConcatSize) (xs ++ ys).size === xs.size + ys.size (TreeSizeEmpty) Empty.treeSize === 0 (TreeSizeNonEmpty) NonEmpty(x, l, r).treeSize === l.treeSize + r.treeSize + 1 (ToListEmpty) Empty.toList === nil (ToListNonEmpty) NonEmpty(x, l, r).toList === l.toList ++ (x :: r.toList) Let us prove the following lemma for all s: IntSet: (ToListSize) s.toList.size === s.treeSize We prove it by induction on s. Base case: s is Empty. Therefore, we need to prove: Empty.toList.size === Empty.treeSize Starting from the left hand-side (Empty.toList.size), what exact sequence of lemmas should we apply to get the right hand-side (Empty.treeSize)?
A. SizeNil, ToListEmpty, TreeSizeEmpty
