Explain how to use an AVL tree to sort n comparable elements in O(n log n) time.
Homework Answers
insert n elements into an AVL tree. => inserting each element takes O(log(n)) => so, total time complexity of inserting all n elements is O(n log(n)) finding and removing min element from AVL tree takes O(log n) finding and removing min element, n times gives all n elements in sorted order. total time complexity for this operation is O(n log(n)) so, total time complexity is O(n log(n)) + O(n log(n)) = O(n log(n)) this is how we can sort n elements using AVL tree in O(n log(n)) time

True or false? (a) An insertion in an AVL tree with n nodes requires Θ (log(n)) rotations. (b) A set of numbers are inserted into an empty BST in sorted order and inserted into an empty AVL tree in random order. Listing all elements in sorted order from the BST is O (n), while listing them in sorted order from the AVL tree is O (log(n)). (c) If items are inserted into an empty BST in sorted order, then the...

fill in the blank Binary Search Tree AVL Tree Red-Black Tree complexity O(log N), O(N) in the worst case O(log N) O(log N) Advantages - Increasing and decreasing order traversal is easy - Can be implemented - The complexity remains O(Log N) for a large number of input data. - Insertion and deletion operation is very efficient - The complexity remains O(Log N) for a large number of input data. Disadvantages - The complexity is O(N) in the worst case...
