WebUsing the position of the median, we can locate or find out the Kth smallest element. If the position of the median is equal to K, it gives the value of Kth smallest element. If the position of the median is less than K, it refers to the fact that the Kth smallest element is in the left subtree of the current median. phillip gordon buck

WebThe answer is simple: If there are root-> rightCount nodes in the right subtree, then the root is (root-> rightCount + 1)th largest element in the tree. Think! If (k = root-> rightCount + 1): the root->data is the required kth maximum element and we return this value as an output. Web163 Companies You are given the root of a binary search tree (BST) and an integer val. Find the node in the BST that the node's value equals val and return the subtree rooted with that node. If such a node does not exist, return null. Example 1: Input: root = [4,2,7,1,3], val = 2 Output: [2,1,3] Example 2:

WebAs inorder traversal of BST results in a sorted array, so kth element in inorder traversal is the kth smallest element. Create a list of integers that stores the inorder traversal of BST.
