WebA Binary Search Tree (BST) is a tree where the key values are stored in the internal nodes. The external nodes are null nodes. The keys are ordered lexicographically, i.e. for each internal node all the keys in the left sub-tree are less than the keys in the node, and all the keys in the right sub-tree are greater. WebDynamic Programming Optimal Binary Search Trees Section 3.5 . Some redefinitions of BST • The text, “Foundations of Algorithms” defines the level, height and depth of a tree a little differently than Carrano/Prichard • The depth of a node is the number of edges in the path from the root to the node – This is also the level of the node how do you toast slivered almonds

The cost of finding a BST key is equal to the level of the key (if present in the BST). Output: The optimal cost of constructing BST is 95. 25 lookups of the key 0 will cost 1 each. 20 lookups of the key 2 will cost 2 each.
