WebJan 26, 2024 · In this video, I have explained how to flatten a multilevel doubly linked list using recursion. Given a doubly linked list, which contains nodes that have a next pointer, a previous … WebYou have been given a Binary Search Tree (BST). Your task is to flatten the given BST to a sorted list. More formally, you have to make a right-skewed BST from the given BST, i.e., the left child of all the nodes must be NULL, and the value at the right child must be greater than the current node.

Sorted Link List to BST Practice GeeksforGeeks

WebYour task is to complete the function sortedListToBST (), which takes head of the linked list as an input parameter and returns the root of the BST created. Expected Time Complexity: O (N), N = number of Nodes. Expected Auxiliary Space: O (N), N = number of Nodes. Constraints: 1 ≤ Number of Nodes ≤ 106.
