9. A nice property of splay trees is that each of Find, Insert and Delete takes O(logn) time. TrueFalse? 10. The keys of value N, N-1, N-2... 4, 3, 2, 1 are inserted in this order in a splay tree. What is the final configuration of the tree? What is the cost in Big-Oh notation of each insert operation? 11. Assume now that the next 100 operations will be a mix of only Find1), Find(2) and Find(3), i.e., search in the tree for either the key of value 1, or the key of value 2, or the key of value 3. After each successful search, splaying is performed from the node where the key was found. 12. What are the 3 tree configurations that are possible after these 100 operations are completed? What is the cost in Big-Oh notation of each Find operation? 13. The next operation is Find(N). In terms of Big-Oh notation, is any of the 3 configurations above faster than the others? If so, what is its Big-Oh time complexity? If not what is the Big-Oh time complexity of FindN) in the three configurations?

Scenario We need to write a method that, given a key as an argument, returns the next in order key found in the binary search tree. If the key given as an argument is not found, the method should still return the next in order key. If the binary tree is empty or all the stored keys are smaller than the argument, then the return value should be empty. For example, using a collection of {10,13,52,67,68,83} stored in the binary...

PYTHON QUESTION... Building a Binary Tree with extended Binary Search Tree and AVL tree. Create a class called MyTree with the methods __init__(x), getLeft(), getRight(), getData(), insert(x) and getHeight(). Each child should itself be a MyTree object. The height of a leaf node should be zero. The insert(x) method should return the node that occupies the original node's position in the tree. Create a class called MyBST that extends MyTree. Override the method insert(x) to meet the definitions of a...

The rules are:
• Leaf Split: In case a leaf node needs to be split during
insertion and n is even, the left node should get the extra key.
E.g, if n = 2 and we insert a key 4 into a node [1,5], then the
resulting nodes should be [1,4] and [5]. For odd values of n we can
always evenly split the keys between the two nodes. In both cases
the value inserted into the parent is the...
