WebThe k'th largest element can be retrieved in O(1) time. The additional space used by the program is O(k). 2. Using Self-balancing BST. Another solution is to use a self-balancing BST. The basic idea for processing a new element remains the same. The k'th largest element will be the smallest element in WebDec 17, 2024 · Suppose we have one binary search tree. We have to find the minimum element in binary search tree. So if the BST is like below −. The minimum element will be 1. As we know that the left subtree always holds the smaller elements. So if we traverse through the left subtree again and again until left is null, we can find the smallest element ... ipss int-2WebThe 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. ipss int-1

"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. Do inorder traversal. If the root is not null recursively do inorder traversal for the left child. Insert the current node’s data to the list. " - In a bst the smallest element is present at
