WebGiven a BST and a positive number k, find the k'th largest node in the BST.. For example, consider the following binary search tree. If k = 2, the k'th largest node is 20.. Practice this problem. We know that an inorder traversal of a binary search tree returns the nodes in ascending order. To find the k'th smallest node, we can perform inorder traversal and … WebStart from the root and keep traversing the binary tree until the root becomes NULL. Retrieve the height of left and right subtrees using height () function. If the difference is more than ‘1’: return false. As the tree does not satisfy the balance condition. Check the balance condition for left and right subtrees recursively. Print the result.
WebYou are given a BST (Binary search tree) with’ N’ number of nodes and a value ‘X’. Your task is to find the greatest value node of the BST which is smaller than or equal to ‘X’. Note :‘X’ is not smaller than the smallest node of BST . For example: WebComplexity Analysis of Insert into a Binary Search Tree Leetcode Solution Time Complexity. O(H) = Height of BST = logN (where N = number of nodes in BST) in average cases(as we make logN recursive calls). But O(N) in the worst case when the tree is a skewed one. Because in case the tree is skewed, the search becomes a linear one. …
