Suppose a bst is constructed by repeatedly inserting distinct keys into the tree. Argue that the number of nodes examined when searching for a key is equal to one more than the number examined when inserting that key. Prove or disprove: deleting keys a and y from a bst is commutative. In other words, it does not matter which order the keys are deleted. The final trees will be identical. If true, provide a proof. If false, provide a counterexample....

Let TB and T2-3 be, respectively, a classical binary search tree and a 2-3 tree constructed for the same list of keys inserted in the corresponding trees in the same order. True or false: Searching for the same key in T2-3 always takes fewer or the same number of key comparisons as searching in Tg?

Suppose you started with an empty binary search tree. We've seen previously that inserting the keys 1, 2, 3, 4, 5, 6, 7 (in that order) would lead to a binary search tree whose shape we called degenerate. Propose a second ordering of the same keys that would also lead to a degenerate-shaped binary search tree. If possible, propose a third ordering of the same keys that would also lead to a degenerate-shaped binary search tree. If there are no...

In general, assuming a balanced BST with n nodes (A balanced binary tree has roughly the same number of nodes in the left and right subtrees of the root), what is the maximum number of operations required to search for a key? Please notice that the tree in this exercise is not balanced. Trace the algorithm for creating a parse tree for the expression (((4 x 8)/6)–3 Please help me understand :(

1.(10 pts) Contrast a heap with a binary search tree by inserting the numbers 60, 30, 40, 50, 20, 10 first in a BST and then in a min-heap. Draw the resulting BST on the left and the heap on the right. You may draw any valid BST or Heap that contain the provided values 2. (5 pts) In section 11.1, the book mentions that heaps are **complete** binary trees, what does that mean? Demonstrate by drawing an example of...
