Trees and Heaps 1. Show that the maximum number of nodes in a binary tree of height h is 2h+1 − 1. 2. A full node is a node with two children. Prove that the number of full nodes plus one is equal to the number of leaves in a nonempty binary tree. 3. What is the minimum number of nodes in an AVL tree of height 15? 4. Show the result of inserting 14, 12, 18, 20, 27, 16,...
Write a recursive function that compares two given binary trees. It returns 1 if the two trees are different, and it returns 0 otherwise. The function signature is: int treeDiff (node "a, node *b); Write a recursive function that counts how many nodes in a tree have a single child. The function signature is: int countoneChild(node "root);
a. How can I show that any node of a binary search tree of n nodes can be made the root in at most n − 1 rotations? b. using a, how can I show that any binary search tree can be balanced with at most O(n log n) rotations (“balanced” here means that the lengths of any two paths from root to leaf differ by at most 1)?
C++ Vectors and Binary Search Trees • Write a program that takes from the user n integers and stores them a vector of int. Then, create a function insert After that takes first Value and second Value. This function searches for each occurrence of first Value in the vector and insert the second Value after it in the same vector. The first and second values are taken from the user. • Create another function that creates a Binary Search Tree...
