Q2. What is a Binary Search Tree (BST)?
Ans. 
A Binary Search Tree (BST) is a data structure where each node has at most two children, with the left child being less than the parent and the right child being greater.
• Nodes in a BST are arranged in a hierarchical order where the left subtree of a node contains only nodes with keys less than the node's key, and the right subtree contains only nodes with keys greater than the node's key.

• BST allows for efficient search...read more

Q3. 
Binary Search Tree Insertion
Given the root node of a binary search tree and a positive integer, you need to insert a new node with the given value into the BST so that the resulting tree maintains the pr...read more
Ans. 
Insert a new node with a given value into a binary search tree while maintaining the properties of a BST.
• Traverse the BST starting from the root node and compare the value to be inserted with each node's value to determine the correct position for insertion.

• Insert the new node as a leaf node in the appropriate position to maintain the BST properties.

• Ensure that the resulting tree is a valid binary search tree by follow...read more

Q4. 
Delete Node in Binary Search Tree Problem Statement
You are provided with a Binary Search Tree (BST) containing 'N' nodes with integer data. Your task is to remove a given node from this BST.
A BST is a ...read more
Ans. 
Delete a given node from a Binary Search Tree (BST) and return the inorder traversal of the modified BST.
• Traverse the BST to find the node to be deleted.

• Handle different cases like node with no children, one child, or two children.

• Update the pointers of the parent node and child nodes accordingly.

• Perform inorder traversal after deletion to get the modified BST.

Given a linked list where each node has two pointers: one pointing to the next node and another which can point randomly to any node in the list or ...read more
Ans. 
Yes, the cloning of a linked list with random pointer can be accomplished without utilizing extra space.
• Use a hashmap to store the mapping between original nodes and their corresponding cloned nodes.

• Iterate through the original linked list to create the cloned nodes and update the hashmap.

• Iterate through the original linked list again to set the next and random pointers of the cloned nodes using the hashmap.

• Time comple...read more
