WebJun 22, 2015 · K th largest element in a stream using a self-balancing binary search tree: To solve the problem follow the below idea: Create a self-balancing binary search tree … WebThe basic idea is that traversal the whole tree in an inorder manner and adds the node values in an array and at the end return the ‘k-1’th element of the array. Due to BST property, inorder traversal of BST will in a sorted order( ascending ). Code - Initialize a global array ‘arr’, which stores the elements of the BST.
