Structural induction on binary trees
WebRecursively Defined Sets/Structures and Structural Induction To use structural induction on full binary trees: Basis Step: Show that the result holds for the tree that consists of a single node. Recursive Step: Show that if the statement is true for the trees T1 and T2, then it is true for the tree T1⋄T2 that is formed by the recursive step WebMay 18, 2024 · Structural induction is used to prove that some proposition P(x) holds for all x of some sort of recursively defined structure, such as formulae, lists, or trees—or …

WebExample 2: Binary Trees of Natural Numbers BinTree is the inductive set representing binary trees of natural numbers defined by the following constructors: 1. Leaf : Nat → BinTree. 2. Branch : BinTree × Nat × BinTree → BinTree. BinTree is recursive. The structural induction principle for BinTree is: (∀ n ∈ Nat.
