Binary Search Trees from keys 1 to n

Construct Binary Search Trees from keys 1 to n Problem statement to construct a Binary Search Tree(BST) from keys 1 to n. We are given a list of consecutive numbers from 1 to . Determine the number of binary trees that can be constructed from these numbers. Example for building a Binary Search Tree from keys… Read More »

Sorted Linked List to balanced Binary Search Tree

Sorted Linked List to balanced Binary Search Tree (BST). Problem statement to create a Binary Search Tree from a sorted linked list. Given a singly linked list in a sorted order, create a balanced binary search tree (BST). Example: INPUT: Linked List: 1->5->8->10->12->15->20 OUTUT: 10 / \ 5 15 / \ / \ 1 8 12 20 Create… Read More »

Print common nodes in two Binary Search Trees

Print common nodes in two Binary Search Trees Problem statement to print common nodes in two Binary Search Trees (BST). Given two binary search trees, print all the elements that are common in both the trees. Example: INPUT:Tree 1 10 / \ 5 15 / \ / \ 1 8 12 20 Tree 2 7… Read More »

Create a BST such that sum of all greater keys is added to its every key

Create a BST such  that sum of all greater keys is added to its every key. Problem statement to construct a Binary Search Tree (BST) such  that sum of all greater keys is added to its every key: Given a balanced binary search tree (BST), build a binary search tree such that all nodes in original… Read More »

Check identical Binary Search Tree (BST)

Check identical Binary Search Tree (BST) without building a tree Problem statement to check identical Binary Search Tree (BSTs) without building a tree. We are given two arrays of integers from each of which we have to make a binary search tree(BST). We need to determine whether these binary search trees (BSTs) will be identical… Read More »
