OOP is a programming paradigm that focuses on objects and their interactions.
Encapsulation: bundling data and methods that operate on that data within one unit
Inheritance: creating new classes from existing ones, inheriting their properties and methods
Polymorphism: ability of objects to take on many forms, allowing for flexibility and extensibility
Abstraction: hiding implementation details and only exposing necess...
Yes, I have implemented a thread library.
Implemented a user-level thread library using POSIX threads.
Used mutexes and condition variables for synchronization.
Implemented thread creation, joining, and cancellation.
Implemented thread-local storage using pthread_key_create and pthread_setspecific.
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are the same type of object.
It simplifies code and makes it more flexible.
Examples include method overloading and overriding, and interfaces in Java.
Polymorphism is a key concept in object-oriented programming.

It involves putting plans into action and making sure they are carried out effectively.
Implementation can involve the use of technology, personnel, or other resources.
Examples of implementation include launching a new...
Count the number of full nodes in a binary tree.
A full node has both non-null left and right children.
Traverse the tree recursively and count the full nodes.
If a node has both left and right children, increment the count and traverse its children.
If a node has only one child or no child, skip it and traverse its child if it exists.
Given a Y-linked list, find the node at the intersection point.
Traverse both branches of the Y-linked list and compare nodes.
Use a hash table to store visited nodes and check for intersection.
If one branch is longer, traverse it until it matches the length of the other branch.
Remove duplicate characters from a string while preserving order.
Create an empty string to hold the result.
Iterate through each character in the input string.
If the character is not already in the result string, add it.
Return the result string.
Traverse a binary tree in spiral order, alternating between left-to-right and right-to-left at each level.
Use two stacks: one for the current level and one for the next level.
Start with the root node in the first stack.
While there are nodes in the current stack, pop nodes and add their children to the next stack in the opposite order.
Switch stacks after each level to alternate the traversal direction.
Example: For ...
Find the lowest common ancestor (LCA) of two nodes in a binary search tree (BST) efficiently.
In a BST, for any node, left children are smaller and right children are larger.
To find LCA of nodes p and q, start from the root.
If both p and q are smaller than the root, LCA lies in the left subtree.
If both p and q are larger than the root, LCA lies in the right subtree.
If one is on the left and the other is on the righ...

- Ans.
Polymorphism allows methods to do different things based on the object, while inheritance enables classes to share properties and methods.
Polymorphism allows for method overriding and overloading.
Example of polymorphism: A base class 'Animal' has a method 'sound()', and subclasses 'Dog' and 'Cat' implement it differently.
Inheritance allows a class to inherit properties and methods from another class.
Example of inherita...

- Ans.
To delete a node from a singly or doubly linked list, update the pointers of the previous and next nodes.
For a singly linked list, update the next pointer of the previous node to skip the node to be deleted.
For a doubly linked list, update the next pointer of the previous node and the previous pointer of the next node to skip the node to be deleted.
