Construct BST from its given Level Order Traversal

Given the level order traversal of a Binary Search Tree, write an algorithm to construct the Binary Search Tree or BST from ITS given level order traversal. Example Input levelOrder[] = {18, 12, 20, 8, 15, 25, 5, 9, 22, 31} Output In-order : 5 8 9 12 15 18 …
