Ans. 
Binary lifting ancestors problem involves finding the k-th ancestor of a node in a binary tree efficiently.
• Binary lifting is a technique used to find ancestors in a binary tree.

• It involves precomputing the ancestors of each node using dynamic programming.

• The k-th ancestor of a node can be found by repeatedly jumping up the tree in powers of 2.

• Example: Given a binary tree with nodes 1, 2, 3, 4, 5, 6, 7, the 2nd ancestor

Q1. What is Object oriented programming language.
Ans. 
Object-oriented programming is a programming paradigm that uses objects to represent and manipulate data.
• Object-oriented programming focuses on creating reusable code by breaking down programs into objects.

• Objects have properties (attributes) and behaviors (methods) that can be accessed and modified.

• Encapsulation, inheritance, and polymorphism are key concepts in object-oriented programming.

• Examples of object-oriented ...read more
