Use two pointers to find the nth element from the end of a linked list.
Use two pointers, one moving n steps ahead of the other
When the first pointer reaches the end, the second pointer will be at the nth element from the end
HashMap is not thread-safe while ConcurrentHashMap is thread-safe and allows concurrent access.
HashMap is not thread-safe and can lead to ConcurrentModificationException if accessed by multiple threads simultaneously.
ConcurrentHashMap allows concurrent access by multiple threads without the need for external synchronization.
ConcurrentHashMap achieves thread-safety by dividing the map into segments, allowing multiple th...
I appeared for an interview in Feb 2025, where I was asked the following questions.
Redux is a predictable state container for JavaScript apps, often used with React for managing application state.
Centralized state management: Redux maintains the application state in a single store, making it easier to manage and debug.
Actions and reducers: Actions are payloads of information that send data from the application to the store, while reducers specify how the state changes in response to actions.

Closure is a function that has access to variables in its outer scope, even after the outer function has returned.
A closure can be used to create private variables and methods in JavaScript.
Closures can be used to implement partial application and currying.
Event listeners and callbacks often use closures to maintain state between function calls.
Closures can be used to create memoized functions that cache their results
Callbacks hell is a situation where nested callbacks make code hard to read and maintain. Promises, observables, and async/await are solutions to this problem.
Callbacks hell occurs when there are too many nested callbacks in code.
Promises are a way to handle asynchronous operations in JavaScript.
Observables are similar to promises but can handle multiple values over time.
Async/await is a syntax for writing asynchronous
Higher order functions are functions that take other functions as arguments or return functions as their result.
Higher order functions allow for more flexible and reusable code.
They can be used for tasks such as filtering, mapping, and reducing arrays.
Examples include Array.prototype.map(), Array.prototype.filter(), and Array.prototype.reduce().
OOPs in JavaScript is a programming paradigm that uses objects to represent real-world entities. Functional programming is a paradigm that uses functions to perform tasks.
OOPs in JavaScript involves creating objects that have properties and methods.
Functional programming involves creating functions that take input and produce output without modifying the input.
OOPs focuses on encapsulation, inheritance, and polymorphis...
Event loop is a mechanism that allows JavaScript to perform non-blocking I/O operations.
Event loop is responsible for handling asynchronous callbacks in JavaScript.
Tasks in the queue can be either microtasks or macrotasks.
Microtasks are executed before macrotasks.
Examples of macrotasks include setTimeout, setInterval, and I/O operations.
Examples of microtasks include Promise callbacks and mutation observer callbacks.
Output of the code in JavaScript
Need to see the code to determine output
Output can vary based on input and logic
Can use console.log() to print output
Browsers use rendering engines to interpret HTML, CSS, and JavaScript to display web pages.
Browsers use rendering engines to interpret HTML, CSS, and JavaScript.
The rendering engine parses the HTML and creates a DOM tree.
The rendering engine then applies CSS rules to the DOM tree to create a render tree.
The render tree is then laid out to determine the position of each element on the page.
Finally, the rendering engine ...
