RxJS is a library for reactive programming using Observables to handle asynchronous data streams.
RxJS stands for Reactive Extensions for JavaScript.
It allows you to work with asynchronous data streams and handle events.
RxJS provides operators to transform, filter, combine, and create observables.
Example: Using RxJS to handle user input events in a web application.
Authentication verifies the identity of a user, while authorization determines what a user can access.
Authentication confirms the user's identity through credentials like passwords or biometrics
Authorization controls the user's access to resources or features based on their identity and permissions
Example: Logging into a website with a username and password is authentication, while being able to view/edit specific...
Promises are objects representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained using .then() to handle success and .catch() to handle errors.
final is a keyword in Java used to declare constants, while finalize is a method in Java used for cleanup operations.
final is used to declare constants in Java
final variables cannot be reassigned

Cloning is the process of creating an exact copy of an object or organism.
There are two main types of cloning: reproductive cloning and therapeutic cloning.
Reproductive cloning involves creating a genetically identical copy of an organism, such as Dolly the sheep.
Therapeutic cloning is the process of creating embryonic stem cells for medical research and treatment.
Cloning can also refer to making copies of softwar...

21 students were shortlisted from the 1st MCQ round and in this round we were asked to write the codes (function only) of 3 questions in 1 hour time.
You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Given an array/list 'ARR' consisting of 'N' integers, your task is to find the majority element in the array. If there is no majority element present, return -1.
You are provided with a non-empty binary tree in which each node contains a non-negative integer value. Your task is to find and return the maximum ...
Find the maximum path sum between two leaf nodes in a binary tree.
Traverse the tree to find the maximum path sum between two leaf nodes.
Keep track of the maximum sum found so far.
Consider all possible paths between leaf nodes.
Handle cases where the tree has only a single leaf node.
Implement a recursive function to calculate the maximum path sum.

Find the N-th node from the end of a Singly Linked List of integers.
Traverse the list to find the length L of the list.
Calculate the position of the N-th node from the beginning as L - N + 1.
Traverse the list again to reach the calculated position and return the node's value.
You are given a binary tree consisting of distinct integers and two nodes, X
and Y

Grammar in compiler design defines the syntax and structure of a programming language.
Grammar specifies the rules for forming valid statements in a programming language.
It consists of a set of production rules that define how valid programs can be constructed.
There are different types of grammars such as context-free grammar, regular grammar, etc.
Example: In C programming language, the grammar specifies that a for loop...
A token in compiler design is a basic unit of syntax that the compiler can understand and process.
Tokens are the smallest units of a program that are meaningful to the compiler.
Examples of tokens include keywords, identifiers, operators, and punctuation symbols.
Tokens are generated by the lexical analysis phase of the compiler.
Tokens are used by the parser to build the abstract syntax tree of the program.

Technical round with questions on DSA and Compiler Design mainly. He told me that you’ll be having your final HR round in some time. I knew that I was going well because he seemed to be quite satisfied with my answers.
You are given an arbitrary binary tree consisting of N nodes, each associated with an integer value from 1 to 9. Each root-to-leaf path can be considered a number formed by concat...
A regular language is a language that can be recognized by a finite automaton.
Regular languages can be described by regular expressions.
Regular languages are closed under union, concatenation, and Kleene star operations.
Examples of regular languages include the set of all strings over an alphabet that contain an even number of 'a's.
NP problems are decision problems that can be verified in polynomial time, while NP-Hard problems are at least as hard as the hardest problems in NP.
NP problems can be verified in polynomial time but not necessarily solved in polynomial time.
NP-Hard problems are at least as hard as the hardest problems in NP, but may not be in NP themselves.
Examples of NP problems include the subset sum problem and the traveling salesm...

That was the round for which I’ve been waiting for hours
She was very friendly and nice to talk to. It didn’t seem that I was talking to the HR. It was more like talking to a friend. Finally we discussed about the pay-scale and work culture in Accolite.

TreeSet is a sorted set implementation in Java. WeakHashMap is a hash table-based Map implementation with weak keys.
TreeSet is implemented using a tree structure and maintains elements in sorted order.
WeakHashMap is a Map implementation that allows keys to be garbage collected when they are no longer referenced.
WeakHashMap is useful for caching or memoization where the keys are not always needed and can be garbage coll...
Comparable and Comparator are interfaces used for sorting objects in Java.
Comparable interface is used to define the natural ordering of objects based on their own class.
Comparator interface is used to define the ordering of objects based on a separate class.
Comparable interface has compareTo() method while Comparator interface has compare() method.
Comparable interface is implemented by the class whose objects need to ...
