There are two rounds in the interview process: the first round consists of one data structures and algorithms question based on trees.

Q1. What is the problem statement for Binary Search Trees in data structures and algorithms?
Ans. 
Binary Search Trees (BST) enable efficient data storage and retrieval through a hierarchical structure, optimizing search operations.
• A BST is a binary tree where each node has at most two children.

• For any given node, all values in the left subtree are less, and all values in the right subtree are greater.

• Searching for a value in a BST has an average time complexity of O(log n).

• Insertion and deletion operations also mai...read more
