Sum of k smallest elements in Binary Search Tree

Given a binary search tree and a integer k our task is to find out sum of all the elements which is less or equal to the k th smallest element

algorithm

Find k-th smallest element in Binary Search Tree

Given root of the tree and k as input, output K th smallest element. We reduce the time complexity from O(N) to O(log N).

algorithm

Algorithm to convert Binary Search Tree into Balanced Binary Search Tree

In this article, we will explore an algorithm to convert a Binary Search Tree (BST) into a Balanced Binary Search Tree in linear time O(N).

algorithm

Algorithm for finding minimum or maximum element in Binary Search Tree【O(log V) / O(V)】

Binary Search Tree is a node-based binary tree data structure and finding the maximum or minimum element take O(log N) in average and can take O(N) in the worst case to O(1) in the best case.

data structure

Understand everything about Binary Search Tree

Binary search tree is a data structure that quickly allows us to maintain a sorted list of numbers in a tree data structure. It can be used to search for the presence of a number in O(log(n)) time and a simple traversal gives the numbers in sorted order.
