WebFirst, we find the middle of the linked list and assign it as the BST’s root. We get the middle node using the two-pointer (slow and fast) approach. Then, we divide the list into two halves, left and right. We recursively do the following to find the left and right subtree: Find the middle of the left subtree and make it the root. WebJan 10, 2024 · 1) If Linked list is empty then make the node as head and return it. 2) If the value of the node to be inserted is smaller than the value of the head node, then insert the node at the start and make it head. 3) In a loop, find the appropriate node after which the input node (let 9) is to be inserted.

WebA binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree whose internal nodes each store a value greater than all the values in the node's left subtree and less than those in its right subtree. Follow Up : Can you solve this in O(N) time and O(H) space complexity? Input Format : WebBinary Search Tree (BST) is a rooted binary tree, whose nodes each store a key (and optionally, an associated value) and each have two distinguished sub-trees, commonly denoted left and right. ...
