WebProof by induction - The number of leaves in a binary tree of height h is atmost 2^h. WebThe basic framework for induction is as follows: given a sequence of statements P (0), P (1), P (2), we'll prove that P (0) is true (the base case ), and then prove that for all k, P (k) ⇒ P (k+1) (the induction step ). We then conclude that P (n) is in fact true for all n. 1.1. Why induction works

WebWe aim to prove that a perfect binary tree of height h has 2 (h +1)-1 nodes. We go by structural induction. Base case. The empty tree. The single node has height -1. 2-1+1-1 = 2 0-1 = 1-1 = 0 so the base case holds for the single element.

WebYou come up with the inductive hypothesis using the same method you would for any other inductive proof. You have a base case for h ( t) = 0 and h ( t) = 1. You want to show that it's true for all values of h ( t), so suppose that it's true for h ( t) = k (inductive hypothesis) and use that to show that it's true for h ( t) = k + 1. – Joe WebInductive Step. We must prove that the inductive hypothesis is true for height . Let . Note that the theorem is true (by the inductive hypothesis) of the subtrees of the root, since they have height . Thus, the inductive hypothesis is true for height and, hence (by induction), true for all heights. A complete binary tree of nodes has height .

WebTo prove this claim using induction, we first need to identify our induction variable. For complex objects like trees, the induction variable measures the size of the object. For trees, I usually use the height. The number of nodes also works. So our proof would start out like this: Proof: by induction on h, which is the height of the llama tree.
