Proof by induction tree

WebProof: Fix m then proceed by induction on n. If n < m, then if q > 0 we have n = qm+r ≥ 1⋅m ≥ m, a contradiction. So in this case q = 0 is the only solution, and since n = qm + r = r we have a unique choice of r = n. If n ≥ m, by the induction hypothesis there is a unique q' and r' such that n-m = q'm+r' where 0≤r' WebTree Problem • f(n) is the maximum number of leaf nodes in a binary tree of height n Recall: • In a binary tree, each node has at most two children • A leaf node is a node with no children • The height of a tree is the length of the longest path from the root to a leaf node. 11

Inductive step: Suppose every tree with n vertices has n - 1 edges. Given a tree T with n + 1 vertices, this tree must be equivalent to a tree of n vertices, T', plus 1 leaf node. By the hypothesis, edges (T') = n - 1.

WebHere is another example proof by structural induction, this time using the definition of trees. We proved this in lecture 21 but it has been moved here. Definition: We say that a tree \(t \in T\) is balanced of height \(k\) if either 1. WebSince jV(C)j 4, for each child h of (G;k), by the induction hypothesis, the number of leaves of T that are descendants of h is at most 4k jV (C) +3.So T has at most 4 jV (C)3 k4k +3 = 4 leaves. Therefore, the search tree algorithms runs in time O(4knc) for some con- stant c.
