WebMar 13, 2024 · Python Binary Search Tree: Find the k th smallest element in a given a binary search tree (BST) Last update on March 13 2024 13:01:33 (UTC/GMT +8 hours) Python Binary Search Tree: Exercise-6 with Solution. Write a Python program to find the k th smallest element in a given binary search tree. 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.
