Binary Tree

Problem Statement: Given a root of Binary Tree, where the nodes have integer values. Return the size of the largest subtree of the binary tree which is also a BST. A binary search tree (BST) is a b...

Problem Statement: Implement the BSTIterator class that represents an iterator over the inorder traversal of a Binary Search Tree: BSTIterator(TreeNode root): Initialises an object of the BSTIterat...

Problem Statement: Given the traversal sequences (such as preorder, inorder, or postorder) of a binary tree, the task is to determine if it's possible to construct a unique binary tree from these t...

Problem Statement: Given the root of a Binary Tree, create a function that performs a postorder traversal using only one stack and returns an array containing the traversal sequence. Examples Examp...

Problem Statement: Given the root of a Binary Tree, write a function that returns an array containing the inorder traversal of the tree using an iterative approach with a stack. Examples Example 1:...

Problem Statement: Given the root of a Binary Tree, write a function that returns an array containing the preorder traversal of the tree using an iterative approach with a stack. Examples Example 1...

Problem Statement: Given the root of a Binary Tree, create a function that performs a postorder traversal using two stacks and returns an array containing the traversal sequence. Examples Example 1...

Problem Statement: Given a binary tree, a node from the tree, and an integer ‘K’, find all nodes that are at a distance ‘K’ from the given node and return the list of these nodes. Examples...

In Java, a binary tree is structured using references to other nodes, forming a hierarchical arrangement where each node can refer to at most two other nodes: a left child and a right child. This r...

In C++, a binary tree is represented using pointers, forming a hierarchical structure where each node can point to two further nodes: a left child and a right child. This representation uses pointe...
