Hashmap coding questions
Multicollinear behavior in independent variables occurs when two or more independent variables in a regression model are highly correlated with each other.
Multicollinearity can lead to unstable estimates of the coefficients in a regression model.
It can make it difficult to determine the individual effect of each independent variable on the dependent variable.
Common indicators of multicollinearity include high correlati...
Seasonality in TSA refers to patterns that repeat at regular intervals within a time series data.
Seasonality is a characteristic of time series data where patterns repeat at fixed intervals, such as daily, weekly, monthly, or yearly.
It can be caused by factors like weather, holidays, or cultural events.
For example, retail sales may exhibit seasonality with higher sales during the holiday season each year.

It was a MCQ based questions on JavaScript, React, Redux
1 Coding question from string topic
Redux is a predictable state container for JavaScript apps. It helps manage the state of your application in a more organized way.
Redux is typically used in large-scale applications with complex state management needs
It helps in maintaining a single source of truth for the state of your application
Redux works well with React, but can be used with any other JavaScript framework or library
Actions are dispatched to update
No, it is not optimal to use redux for single state
Redux is typically used for managing complex state across multiple components
Using redux for a single state can add unnecessary complexity to the codebase
Consider using React's built-in state management for simpler cases
SCSS is a preprocessor scripting language that is a superset of CSS, adding features like variables, nesting, and mixins.
Variables allow for reusable values throughout a stylesheet
Nesting helps to keep styles organized and easier to read
Mixins allow for reusable blocks of styles to be included in other selectors
SCSS supports operations like math calculations and functions
SCSS can be compiled into regular CSS for use in
Websocket i.o is a JavaScript library that enables real-time, bidirectional and event-based communication between the browser and the server.
Allows for real-time communication between client and server
Enables bidirectional data transfer
Supports event-based communication
Used for applications requiring real-time updates like chat applications, online gaming, live tracking, etc.
forIn loop iterates over the enumerable properties of an object, while forOf loop iterates over the values of an iterable object.
forIn loop is used for iterating over object properties, while forOf loop is used for iterating over array elements.
forIn loop can be used with objects, while forOf loop can be used with arrays, strings, maps, sets, etc.
Example: forIn loop - for (let key in object) { console.log(key); }

The filter method is a built-in JavaScript method used to create a new array with all elements that pass a certain condition.
Filter method is more concise and readable compared to for loop
Filter method is more declarative and functional programming oriented
Example: const numbers = [1, 2, 3, 4, 5]; const evenNumbers = numbers.filter(num => num % 2 === 0);
Example: const words = ['hello', 'world', 'example']; const shortW

OOPs is a programming paradigm that uses objects to represent real-world entities. Java is an OOPs language.
OOPs stands for Object-Oriented Programming System
Java is a class-based OOPs language
Encapsulation, Inheritance, Polymorphism, and Abstraction are the four pillars of OOPs
Objects have state and behavior
Java supports interfaces, which allow for multiple inheritance
Example: A car can be represented as an object wit...
Java solves machine dependency by using bytecode and virtual machine.
Java code is compiled into bytecode which is platform-independent
The bytecode is executed by the Java Virtual Machine (JVM) which is platform-specific
JVM translates bytecode into machine code for the specific platform
This allows Java code to run on any platform with a JVM installed
Example: A Java program compiled on Windows can run on Linux or Mac as
