WebHere pre-order traversal of a binary search tree is given in array. So the 1st element of pre-order array will root of BST.We will find the left part of BST and right part of BST.All the element in pre-order array is lesser than root will be left node and All the element in pre-order array is greater then root will be right node. WebA Binary Search Tree (BST) is a binary tree in which each vertex has only up to 2 children that satisfies BST property: All vertices in the left subtree of a vertex must hold a value smaller than its own and all vertices in the …
