Which statement is correct? An AVL tree is a balanced binary search tree. An AVL tree is a normal binary search tree. An AVL tree is a 2-3 tree. An AVL tree is usually not a binary search tree. Which of the following cases does not exist in runtime complexity theory? Best case Worst Case Average Case Null case. The in-order traversal of a tree yield a sorted listing of elements of the tree in Binary Trees Binary search trees Heaps Binary heaps the concept of order Big O is important because.

Solution:
16. a) An AVL tree is a balanced binary search tree.
In computer science, an AVL tree is a self-balancing binary search tree. It was the first such data structure to be invented. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property.
17. Which of the following case does not exist in complexity theory
d) Null case
18. The In-order traversal of a tree will yield a sorted listing of elements of the tree in
b) Binary search trees
19. The concept of order Big O is importantt because
d) Both A and B
20. c) (b) or (c)
Explanation: everything to the left of x must be < x, and everything to the right of x must be > x.
