apply, call, and bind are methods used to manipulate the context of a function in JavaScript.
apply() - calls a function with a given 'this' value and arguments provided as an array
call() - calls a function with a given 'this' value and arguments provided individually
bind() - creates a new function that, when called, has its 'this' keyword set to the provided value

To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
A linked list is a data structure consisting of nodes where each node points to the next node in the sequence.
Create a Node class with data and next pointer
Initialize a head pointer to null
Add nodes by updating next pointers
Traverse the list by following next pointers

Lookup is used to perform a left outer join in MongoDB, while graphlookup is used to perform recursive graph traversal.
Lookup is used to perform a left outer join between two collections in MongoDB.
Graphlookup is used to perform recursive graph traversal in a collection that contains graph data.
Lookup can only perform a single level join, while graphlookup can perform multiple levels of traversal.
Lookup is faster than
Use a hashmap to count the frequency of each character in a string.
Create a hashmap to store characters as keys and their frequencies as values.
Iterate through the string and update the hashmap accordingly.
Return the hashmap with character frequencies.

It was ok. I was not able to solve all the questions.
To remove the last element from a linked list, iterate to the second last node and update its next pointer to null.

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization helps in minimizing data redundancy by dividing the database into multiple tables.
It ensures data integrity by avoiding update anomalies.
Normalization is achieved through a series of rules called normal forms, such as 1NF, 2NF, 3NF, etc.
Example: In a database, instead of storing customer details i...

Allows accessing metadata of types and members at runtime
Enables dynamic instantiation of objects
Facilitates invoking methods dynamically

It was a test that had like basic c questions that one needs to practice, basic logical reasoning and Mathematics, a couple of English grammar questions
There is a coding round with 4 questions 3 coding questions and one find the output of the c program question, one easy question, 2 medium questions one medium to hard level.Two linear data structure questions one array one linked list and one tree question.
Another coding test with 3 questions medium to hard level questions from trees and linked lists, with optimisation required
Quantitative arithmetic,verbal reasoning,non-verbal reasoning,etc

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPS focuses on creating objects that interact with each other to solve complex problems
Key principles include encapsulation, inheritance, polymorphism, and abstraction
Encapsulation ensures that the internal state of an object is hidden from the outside world
Inheritance allows a class to inherit...
