Optimal bst
Webmust an optimal BST be complete/perfect? Yes. In order to get the fastest possible search for a given tree, all of the tree's nodes must be equally distributed; i.e. the tree must be as short as possible.

WebWe have to find the Optimal BST which is defined as a BST that has the least cost of searching the elements. Cost of Searching one Node: The cost of searching one node is defined as the height of the node in the Binary Search Tree multiplied by the frequency of searching that node. Cost of BST
