Ajax calls allow for asynchronous communication between client and server without reloading the page.
Ajax stands for Asynchronous JavaScript and XML
Uses XMLHttpRequest object to send and receive data
Allows for partial page updates without reloading the entire page
Can handle data in various formats such as JSON, XML, HTML, and plain text
Example: $.ajax({url: 'example.com', success: function(data){console.log(data)}});
REST is lightweight and uses HTTP while SOAP is XML-based and has more features.
REST uses HTTP methods like GET, POST, PUT, DELETE while SOAP uses XML messaging.
REST is stateless while SOAP can maintain state.
REST is faster and easier to use while SOAP is more secure and reliable.
REST is used for web services while SOAP is used for enterprise-level services.
Example of REST: Twitter API. Example of SOAP: Amazon Web Serv
GET and POST are HTTP methods used for sending data to a server.
GET is used to retrieve data from a server
POST is used to submit data to a server
GET requests can be cached and bookmarked
POST requests are not cached and cannot be bookmarked
GET requests have length restrictions
POST requests have no length restrictions
GET requests are less secure than POST requests
Observer pattern is a design pattern in which an object maintains a list of its dependents and notifies them automatically of any state changes.
Also known as publish-subscribe pattern
Used in event-driven systems
Allows loose coupling between objects
Example: A weather station broadcasts weather updates to multiple displays
Example: A stock market ticker notifies multiple investors of stock price changes
Singleton is a design pattern that restricts the instantiation of a class to a single object.
Singleton ensures that only one instance of a class exists in the entire application.
It provides a global point of access to the instance.
Commonly used in scenarios where a single instance needs to coordinate actions across the system.
Example: Database connection manager, logger, configuration manager.
Immutable in Java refers to objects whose state cannot be changed after creation.
String, Integer, and other wrapper classes are immutable in Java.
Immutable objects are thread-safe and can be shared without synchronization.
To create an immutable class, make all fields final and private, and don't provide setters.
Examples of immutable classes in Java include LocalDate, LocalTime, and LocalDateTime.
Creating immutable in Java
Use final keyword to make variables immutable
Use private constructor to prevent object modification
Use defensive copying to prevent modification of mutable objects
Use enum to create immutable objects
Use String class to create immutable strings
Dependency injection is a design pattern that allows objects to receive dependencies rather than creating them internally.
It helps to decouple the code and makes it more testable and maintainable.
It allows for easier swapping of dependencies without changing the code.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.
Example: Instead of creating a database co...
CORS stands for Cross-Origin Resource Sharing. It is a security feature implemented in web browsers to restrict access to resources from different origins.
CORS allows web servers to specify which origins are allowed to access its resources
It is implemented using HTTP headers
CORS prevents malicious websites from accessing sensitive data from other websites
Examples of resources that may be restricted by CORS include cook
CORS can be overcome by configuring the server to allow cross-origin requests.
Configure the server to include the Access-Control-Allow-Origin header
Use JSONP (JSON with Padding) to bypass CORS restrictions
Use a proxy server to make the request on behalf of the client
Use a browser extension to disable CORS restrictions during development
Use a server-side proxy to forward requests to the target server

Need more context. What needs to be done with the large rectangle?
What are the dimensions of the rectangle?
Is it a 2D or 3D object?
What is the context of the problem?
Are there any constraints or limitations?
What tools or programming languages can be used?
Derive a formula to determine how many smaller rectangles fit into a bigger rectangle given their dimensions.
Calculate the number of times the smaller rectangle can fit into the bigger rectangle horizontally and vertically
Divide the width of the bigger rectangle by the width of the smaller rectangle to get the horizontal count
Divide the height of the bigger rectangle by the height of the smaller rectangle to get the ve...
At least 4 points are required to draw a rectangle.
A rectangle has 4 sides and 4 corners, so at least 4 points are needed to define those corners.
The points must be arranged in a specific order to form a closed shape with 4 sides.
Additional points can be used to add details or modify the shape of the rectangle.
The number of points required may vary depending on the software or tool used to draw the rectangle.
Answering how to calculate new coordinates of a scaled rectangle and providing a program for it.
To calculate new coordinates, multiply the original coordinates by the scaling factor
Scaling factor can be calculated by dividing the new length/breadth by the original length/breadth
Program can take input of original coordinates, scaling factor, and output new coordinates
Example: Original coordinates: (0,0), (0,5), (5,5), (...

The interviewer understand the current problem statement I was working on.
Asked the clarifying questions and alternative approaches to solve the same and their tradeoffs.
Also, asked about the technologies I was using in depth and reason for choosing the same.
You have a car with a gas tank of infinite capacity. There are 'N' gas stations located along a circular route, numbered from 0 to N-1. You begin your journey with an empty tank...
Find the starting gas station index to complete a circular route with gas and cost arrays.
Iterate through gas stations, keeping track of gas remaining after each station
If gas remaining is negative, reset starting station to current station + 1
If total gas remaining at the end is greater than or equal to total cost, return starting station index
